--------------
About AutoCAD
--------------

We know that every AutoCAD installation is different. However each one
requires the configuration of the same basic parameters in order to
function. The examples we use in this manual assume that you have
installed AutoCAD on drive C using the installation defaults. This means for
ACAD 10, 11, 12 that your main AutoCAD directory is \ACAD and all other
directories (i.e., SUPPORT, FONTS, DRV, etc.) fall under it. For ACAD 13 the
default installation directory is \ACADR13\DOS.

We also assume that you are using the AutoCAD created ACADR13.BAT file to
start AutoCAD Release 13 and ACADR12.BAT file to start AutoCAD Release 12.
For AutoCAD Releases 10/386 and 11, it is not as critical to use a batch
file to start the program, however it is much easier.

If you have not configured AutoCAD using defaults, don't worry, you can
still easily install TurboDLDClassic. All you have to do is substitute
your specific sub-directory names with those in our examples.  If you
are using a menuing system or other AutoCAD start-up file, use that when
we reference ACADR13.BAT or ACADR12.BAT.


---------------
About TurboDLD
---------------

Our references to the location of TurboDLD files assume that you have chosen
to install TurboDLDClassic into the \ACADR13\DOS\DRV sub-directory for
AutoCAD Release 13, \ACAD\DRV sub-directory for AutoCAD Release 12, or in
a sub-directory named \ACAD for AutoCAD Release 10 or 11.


What's it do?
-------------

TurboDLDClassic 's main function is to speed up AutoCAD pans, zooms and
redraws. The driver accomplishes this by creating and maintaining a Display
List - a fast-displaying object list of the current drawing - dramatically
increasing performance on pans and zooms.

In addition to offering display list speed enhancement, TurboDLDClassic
provides add-on productivity features - bird's-eye view, drawing viewer,
automatic edge panning,  pop-up text menus, graphics mode text window
and digitizer button programming - to further speed up the use of AutoCAD.


What's the Catch?
-----------------

The only resource used by TurboDLDClassic is memory.  The driver actively
uses about 300Kbytes of RAM from extended memory for its operation. This
memory is drawn from AutoCAD's memory pool and therefore does not affect
normal DOS operation. The driver is loaded by AutoCAD at AutoCAD load time
and is unloaded when AutoCAD is exited.

Additionally, the Display List size can vary from one tenth to three times
the size of the current drawing file. We recommend that you use 8Mb of RAM
with AutoCAD Release 10/386 or 11, and 12Mb for AutoCAD Release 13 or 12.


Thanks for the Memory
---------------------

You may wish to purchase and install additional RAM before installing
TurboDLDClassic, since it shares memory with AutoCAD. If AutoCAD is using
a lot of memory, TurboDLDClassic may not have enough.  If there is
significant hard disk activity while you are using TurboDLDClassic, it may
be an indication that you should add more memory to your system.

*************************************
CHAPTER 1 - PANACEA'S TURBODLDClassic
*************************************


TurboDLDClassic has only two purposes: 1) to speed up AutoCAD REDRAWs, PANs,
and ZOOMs; and 2) to provide a more productive, user-friendly, interface
to AutoCAD (via the features described in Chapter 4 - Features).

The driver is memory-resident and inserts itself between AutoCAD and the
graphics board.  It has no other effect on AutoCAD's operation besides
speeding the program up; it runs with AutoShade 2 with RenderMan and all
versions of 3D Studio, but does not affect the speed of these programs,
since they do not support Display Lists.

Installing TurboDLDClassic does not change any of the AutoCAD program files
or alter any of the drawing files stored on disk.  TurboDLDClassic was
designed to be an easy-to-use, feature-filled product that makes using
AutoCAD faster and more productive, not one that makes AutoCAD more
complicated and difficult to use.

How does TurboDLDClassic make AutoCAD run faster?  There are three things
the driver does to speed operation:

 AutoCAD stores drawings in a hierarchical structure, with simple
  elements intermixed with complex ones.  Every time the screen is updated,
  AutoCAD must decode this structure.  TurboDLDClassic works differently.
  While you are working, it translates the normal hierarchical structure
  into a Display List, a series of vectors or polygon fills.  (The ability
  to support display lists was specifically added to AutoCAD with Release 10
  via the ADI 4.0 interface.)  When you pan or zoom, TurboDLDClassic uses
  the Display List, then writes the resulting vectors to the video board
  hardware.  Since the hierarchical structure does not have to be decoded,
  drawing proceeds very quickly.

 In addition to the Display List, TurboDLDClassic also maintains a Drawing
  Cache. The Drawing Cache is a compressed list which contains the current
  contents of a viewport. This pre-scaled portion of the Display List allows
  for even faster pans and zooms and redraws.

 Lastly, TurboDLDClassic gives you numerous new user-interface features,
  such as a bird's eye view, automatic edge panning, pop-up menus and
  drawing viewer. (See Chapter 4 - TurboDLD Features.)

By how much does TurboDLDClassic increase the speed of AutoCAD? PANs and
ZOOMs, aided by only the Display List, run from two to twelve times
faster than a non-display list driver.  TurboDLDClassic's internal
display list processing can speed things up to the point that REDRAWs
can be up to twenty-five times faster than the graphics drivers shipped
with AutoCAD.



******************************************************
CHAPTER 2 - INSTALLING AND CONFIGURING TURBODLDClassic
******************************************************


Installation is slightly different for older releases of AutoCAD than it
is with AutoCAD Release 12 and 13. Be sure to follow any directions that may
be specific to your particular AutoCAD release.

TurboDLDClassic files will be copied from the installation disk to the
hard drive.


--------------------------
Installing AutoCAD Drivers
--------------------------

Run the TurboDLDClassic installation program.

1.  Insert the install disk in floppy drive A: or B:

2.  At the DOS prompt, type a:\install or b:\install, depending on the drive
    selected.

3.  From the Main Menu, select DRIVER INSTALLATION and then AUTOCAD.

4.  The following options are available, select one:
    ACAD386 Rel 10, 11 (protected mode)
    ACAD Rel 12 (protected mode)
    ACAD Rel 13
    Read Installation Notes

    The default installation directory for AutoCAD R12 is \ACAD\DRV.
    The default installation directory for AutoCAD R13 is \ACADR13\DOS\DRV.

    The required files are copied to the appropriate sub-directory.

5.  Exit the install program and proceed to selecting the driver in AutoCAD.


--------------------------------- NOTE -------------------------------------
If you choose to install the driver files to an alternate sub-directory, you
must alter the ACADDRV (set through ACAD batch file) environment variable.
For Example: SET ACADDRV=\ACAD\OTHER
----------------------------------------------------------------------------



----------------------------------------------------
Selecting the driver for use with AutoCAD 12 or 13
----------------------------------------------------

1.  Run the ADIACAD batch file created in \ACAD\DRV for AutoCAD 12 and
    \ACADR13\DOS\DRV for AutoCAD 13.

2.  Start AutoCAD:

    For AutoCAD 12, run ACADR12 -R, located in the root directory.
    For AutoCAD 13, run ACADR13 -R, located in the root directory.


3.  From the Configuration Menu, choose option 3, Configure Video Display
    from the AutoCAD configuration menu.

4.  Type Y at the "Do you want to select..." message to display the
    available video options for AutoCAD.

5.  Select "TurboDLD Classic Demo - v2.x by Panacea Inc." from the list of
    display options.

6.  Proceed to configuring the TurboDLD driver.

------------------------------  NOTE  --------------------------------------
TurboDLDClassic  usually appears as option 11 in most installations of
AutoCAD Release 12 and 13. If TurboDLD does not appear in the list of
available video drivers, be sure that the AutoCAD environment variables in
your AutoCAD start-up file, ACADDRV in particular, have been properly set
before typing ACADR12 -R or ACADR13 -R.
----------------------------------------------------------------------------


--------------------------------------------------------
Configuring the driver for use with AutoCAD 10/386 or 11
--------------------------------------------------------

1.  Run the ADIACAD batch file in the \ACAD sub-directory and then start
    AutoCAD.

2.  Reconfigure AutoCAD to use TurboDLDClassic by selecting option 5,
    Configure AutoCAD from the AutoCAD main menu.

3.  From the next menu, select option 3, Configure Video Display.
    Choose Item 1, P386 ADI 4.0/4.1 (R11) or ADI P386 (R10), as your display
    device. (For more information, see your AutoCAD "Installation and
    Performance Guide.")

4.  After selecting the proper display device, the TurboDLD Driver
    Configuration menu will appear.

5.  Proceed to configuring the TurboDLD driver.


------------------------------------------------
Configuring the TurboDLD Driver General Overview
------------------------------------------------

Set-up of TurboDLDClassic requires configuration of its various operating
parameters. These parameters have been logically grouped into five menus
based on their interaction with AutoCAD. A quick trip through each menu will
complete the configuration process. Context sensitive help can be obtained
by typing "?" at any menu option. Further details on each menu selection
follows this summary section.

The first menu, Select Graphics Board/Resolution, configures TurboDLDClassic
for the graphics board, and display and rendering resolutions to be used.

 Select Graphics Board
  Selects graphics platform to be used

 Select Display Resolution
  Selects AutoCAD, 3D Studio and AutoShade main display screenresolutions

 Select Rendering Resolution
  Selects AVE Render, 3D Studio and AutoShade rendering resolutions


------------------------------  NOTE  --------------------------------------
Either the Display or Rendering Configuration menu will be displayed,
depending on the type of screen being configured. You will not see both
menu options at the same time.
----------------------------------------------------------------------------


Basic Configuration options set AutoCAD screen characteristics, number of
text lines in the command-line area, font size and screen configuration
mode.

 AutoCAD Text Lines
  Selects number of lines in AutoCAD command prompt area

 Screen Configuration
  Provides a choice of single screen, dual screen or single screen with a
  graphics mode text window.

 Font Selection
  Allows selection of TurboDLDClassic  supplied fonts or Autodesk supplied
  BDF fonts menus and pull-downs.


User Interface options include the parameters for maneuvering within
AutoCAD.

 Double Click
  Sets mouse/digitizer double click detect time.

 BP Highlight Mode
  Controls how the Big Picture is displayed.

 BP Refresh
  Controls the refresh mode of the Big Picture.

 Pop-up Menu Definitions
  Provides user programming of pop-up menus


Expert Configuration options set the function of TurboDLD itself. This menu
allows for customization of the driver for speed or to adjust for memory
constraints.

 Display List
  Enables or disables the display list feature of TurboDLDClassic.

 AutoCAD Logical Drawing Space
  Sets AutoCAD's logical space to 15-bits or 31-bits (R12 only).

 Internal Command Echo
  Enables or disables the echo of TurboDLDClassic internal commands at the
  AutoCAD Command line when such commands are executed.


Saving Your Configuration
-------------------------

Once all options have been set, scroll down to the Save and Exit option
and then press the ENTER key to continue.

Next, configure the AutoCAD screen display characteristics and then type
Y to accept the changes.

Exit to the AutoCAD drawing editor to begin using TurboDLDClassic.

The last step in setting-up TurboDLDClassic is to configure the colors for
AutoCAD. From the AutoCAD Command Line, type DLDCOLOR, to start
CustomColors, TurboDLD's color configuration utility. Make any desired
color changes and then Save the new color palette and then Exit to return
to the drawing editor.



--------------------------------  TIP  -------------------------------------
Help during TurboDLDClassic setup is only a keystroke away. At any time, you
may press the question mark ("?") key to get help information pertaining
to the current prompt. Please note that the DLDSETUP.HLP file must be
present in order for help to appear. If you get an error message, be sure
that the file DLDSETUP.HLP is in the ACADR13\DOS\DRV (R13), ACADR12\DRV
sub-directory (R12), or in the TURBODLD sub-directory (R10/R11). Also, as
mentioned earlier, be sure that there are no references to older DLD drivers
which may cause TurboDLDClassic to look elsewhere for DLDSETUP.HLP.

Also, if at any point during the configuration process you want to change an
item on a previous screen, just press the ESC key to back up. Selecting
NO SAVE, EXIT at the main configuration menu will return you to the AutoCAD
configuration menu without making any changes.
----------------------------------------------------------------------------



------------------------------  NOTE  --------------------------------------
If none of TurboDLDClassic's options are configured, the driver will be
automatically configured as a Generic VGA, with 640 x 480 resolution at
16 colors. All other driver options will assume Panacea's defaults.
----------------------------------------------------------------------------


--------------------------------------
Detailed TurboDLD Driver Configuration
--------------------------------------


Select Graphics Board/Resolution Menu
-------------------------------------
The Select Graphics Board/Resolution menu configures TurboDLDClassic for
video parameters. From this menu, graphics board/type and display and
rendering resolutions for TurboDLDClassic will be determined.

Select Graphics Board allows you to manually select your computer's
graphics board. Select your ATI mach64 card, based on the the
findings of TurboDLDClassic's built-in graphics platform detection utility.
Use the Up and Down arrow keys, and the Pg Up and Pg Dn keys to scroll
through the list and highlight your graphics board. Please note that
graphics boards are listed by both platform type and manufacturer's name,
alphabetically,therefore you may need to scroll to the bottom of the list
to find your particular board.

Press ENTER to accept your choice and return to the Select Graphics
Board/Resolution menu. Select Display Resolution configures the resolution
of the AutoCAD drawing screen. Display screen options are based on the
findings of TurboDLDClassic's graphics platform detection utility. Use the
Up and Down arrow keys, and the Pg Up and Pg Dn keys to scroll through and
highlight the resolution and color option you wish to use.

Press the ENTER key to accept your resolution choice and return to the
Select Graphics Board/Resolution menu.


------------------------------  NOTE  --------------------------------------
When configuring TurboDLDClassic's video options, the Rendering
Board/Resolution options described below will automatically appear ONLY
when configuring the rendering modes of AVE Render, 3D Studio or
AutoShade 2 with RenderMan. Otherwise, the Display Board/Resolution
options will be the only menu choices available.
----------------------------------------------------------------------------


Similar to the Select Display Resolution menu, Select Rendering Resolution
configures the resolution of the AutoCAD rendering screen. Rendering
screen options are also based on the findings of TurboDLDClassic's detection
utility. Use the Up and Down arrow keys, and the Pg Up and Pg Dn keys to
scroll through and highlight the resolution and color option you wish to
use. Press ENTER to accept your choice and return to the Select Graphics
Board/Resolution menu.


------------------------------  NOTE  --------------------------------------
TurboDLDClassic's graphics platform detection utility queries the graphics
card for graphics platform type and installed memory. Based on the
detector's information, TurboDLDClassic will list a set of Display and
Rendering resolutions. Due to the variety of graphics boards and their
specific implementations of platform chip sets, the detector is general
purpose and cannot always be 100% accurate. Therefore, when selecting a
Display or Rendering resolution, be sure to use only resolutions that you
know your graphics board, and monitor, will support. If you are unsure
which resolutions are supported by your graphics board and monitor, refer
to your owner's manual(s).
----------------------------------------------------------------------------


Highlight Return To Previous Menu and press the RETURN key to return to
the Main Configuration Menu.


Basic Configuration Menu
------------------------
The Basic Configuration menu configures TurboDLDClassic's AutoCAD screen
characteristics; text lines; screen mode; and font size.

The first Basic option is the number of text lines you wish to use for the
AutoCAD command line. The default is 3 lines, but values from 1 to 10
can be specified. A number larger than 3 might be useful if you are using
this driver in a high resolution mode with small fonts, eliminating the
need to frequently swap back and forth between the text and graphics
screens.

If you do not want any lines of text at the bottom of the display, use
AutoCAD to disable the command area (see the AutoCAD "Interface,
Installation and Performance Guide" for more information).

The Screen Configuration section is used to tell TurboDLDClassic under which
of three available modes you wish to use AutoCAD -- dual screen, one
monitor for graphics and a second for text; single screen with combined
text and graphics; or single screen with combined text and graphics using
a graphics mode text window.

Use the arrow keys to highlight a choice based on the following explanations
of each mode. Select Dual to run in dual screen mode.

---------------------------------  NOTE  -----------------------------------

Do not select Dual if you don't have a second video board in your system,
unpredictable results will occur. To use dual screens, you must have a
monochrome board installed with a mach64 PCI or VLB accelerator.

----------------------------------------------------------------------------

Choose Single, to run AutoCAD in the standard single screen mode, using a
video mode switch to standard VGA text mode during a flip screen. To
eliminate the video mode switch to text mode and back into high resolution
graphics, choose Text Window on Single to configure the single screen to
use a graphics mode text window. Using graphics mode to display text
allows an instantaneous return from a flip screen. The graphics text window
is especially useful when using large monitors which tend to be slow when
switching modes. A SHELL command will switch to text mode regardless of
the setting.

TurboDLDClassic  provides a choice of fonts to use for AutoCAD menus,
pull-downs, and dialog boxes. For resolutions over 800x600 we recommend
the 12x20 or 12x24 fonts.

Provided by Panacea are 6x8, 8x8, 8x14, 8x16, 12x20 and 12x24 font options.
Also available for use are any of the .BDF fonts, included with AutoCAD
Release 13 or 12, you may have on your system.

To make a font selection, highlight Select Font From List to display a
list of available fonts. Use the Up and Down arrow keys, and the Pg Up
and Pg Dn keys to scroll through the list and highlight the font you
wish to use. Press the ENTER key to return to the Basic Configuration
menu. To limit the available font choices, choose the Select Font Filter
menu selection to choose a .BDF font type from those listed. When you
return to the Select Font From List option again, only those files
matching the filter name will be available for use.


------------------------------  NOTE  --------------------------------------
If you do not see any .BDF font selections listed in the Basic Configuration
menu, you will need to add the following line to your AutoCAD start-up
batch file:

    SET DLDFONT = C:\ACAD\DRV

Please note that .BDF support is not currently available for use with some
boards, most notably, 8514/A-based graphics boards.
----------------------------------------------------------------------------


Highlight Return To Previous Menu and press the RETURN key to return to
the Main Configuration Menu.



-------------------
User Interface Menu
-------------------


Timing Options
--------------
The User Interface options configure the productivity features of
TurboDLDClassic. These features change the way you manuever around AutoCAD
and execute commands.

The first three options, Double Click, Long Click, and Edge Pan Wait, allow
you to set times/delays for TurboDLDClassic features. These times are
measured in hundredths of seconds. PC systems have a timing resolution of
5/100ths of a second, therefore, the entered time is rounded internally by
the driver to most closely approximate the nearest multiple of 5. This means
that a time setting of 23 is the same as a setting of 27, both of which get
rounded to 25 (or one-quarter of a second). In simplest terms, when
adjusting these values, it is best to use multiples of 5.

The first timing option sets the Double Click delay. This time represents
the largest amount of time that can elapse between the release of the
digitizer button and the subsequent press of the same button in order to
detect a double click. Setting this number too low may result in the
computer seeing two separate clicks, while setting the time too high may
slow down response time for single button presses. Values between 10 and 30
are recommended.

The second timing option lets you set the time necessary to determine that a
long click has occurred. Timing starts from the time you press the digitizer
button. For example, with a value of 50 for this option, you will have to
hold down a digitizer button for half a second (50/100ths) in order for a
long click to be registered. Recommended timings for long clicks are between
40 and 80.

The final timing option relates to the Automatic Edge Panning feature of the
TurboDLDClassic. The timing value represents the amount of time that the
cursor must remain in the same position near the edge of the current
viewport for Automatic Edge Panning to be activated (if it's enabled).
A time of 50 is recommended, but any value can be appropriate, depending on
the application at hand.

For example, with edge panning enabled, a value of 0 means that whenever the
cursor approaches the edge of the active viewport, panning will
automatically commence.


Big Picture Options
-------------------
The Big Picture, Panacea's bird's-eye view, can be configured to suit your
needs or allow for better differentiation within a complex drawing.

BP Highlight controls how the current viewport reference in the Big Picture
appears on the screen. Patt Line displays the viewport reference using
dotted lines. XOR Rect uses a contrasting rectangle to display the viewport
reference. The Both option will use a combination of Patt Line and XOR Rect
to display the viewport reference.

In its fastest mode, TurboDLDClassic only refreshes the Big Picture when
objects are added to a drawing, until a DLDREFRESH command is issued.
Moved or erased objects will remain in the Big Picture. Depending on a
drawing's complexity, if BP Refresh is Disabled, the Big Picture could
become confusing, displaying vectors that are actually erased, and no
longer part of the drawing. To configure the Big Picture to be updated as
objects are drawn AND erased, ENABLE the BP Refresh. If speed is a major
concern, DISABLE it.

------------------------------  NOTE  --------------------------------------
Many TurboDLDClassic commands, like DLDBIGPIC, can be preceded by an @
symbol, which tells the driver that an internal command is to be executed.
This gives you the ability to dynamically pull up the bird's-eye during a
drawing command, for example. See Chapter 4 - Features for more information
on the wide variety of TurboDLDClassic commands.

Also, Control Characters, like Ctrl-C, which are used to send special
characters to AutoCAD, can be simulated with a two-character sequence.
For example, when you interrupt an AutoCAD command from the keyboard, you
normally hold down the Ctrl key and press the C key. When you send commands
via the digitizer buttons, it may sometimes be necessary to send Ctrl-C
characters to interrupt the current command and start the one you want.
This can be accomplished by using the carat '^' symbol followed by an
uppercase C, as in ^C^Cline^M, which tells AutoCAD to interrupt the current
command, send the line command, and follow by an Enter (specified by the
^M). Two or three ^C's may be necessary because some AutoCAD commands are
nested. The digitizer button definitions are stored in the DLXBUTTN.DAT file
which resides in the TurboDLDClassic sub-directory.
----------------------------------------------------------------------------


After you have made the desired changes to each menu, press the <F10> key to
advance to the next menu page or the ESC key to go back to the previous one.
Pressing ESC at Menu 1 will bring you back to the User Interface menu,
as will pressing <F10> during Button Menu 8.


-------------------------
Expert Configuration Menu
-------------------------

The Expert Configuration menu sets the basic internal functions of
TurboDLDClassic. Options in this menu allow for customization of the driver
for speed or to adjust for memory constraints.

Display List enables or disables the display list feature of TurboDLDClassic,
the core of the driver's AutoCAD performance boost. This option should
always be set to ENABLE, as disabling the Display List will cause
TurboDLDClassic to run as an ordinary non-display list driver.

Use AutoCAD 31-bit Space, configures TurboDLDClassic for use with AutoCAD
R12's 31-bit logical drawing space. When set to Yes, the driver will use
AutoCAD's extended 31-bit drawing space. Selecting No, will use a 15-bit
drawing space, similar to that of AutoCAD R10/R11.

The 31-bit logical space allows you to extend your Regen-less zooming
ability by a factor of several million, at the cost of more memory.
Additional memory is used by AutoCAD for the drawing space, and by
TurboDLDClassic for the Display List. 31-bit zooming and panning is about
10%-20% slower than for 15-bit logical space.

The Use AutoCAD 31-bit Space setting is ignored for AutoCAD R10/R11
installations as these versions only support a 15-bit logical drawing space.

The echo of TurboDLDClassic internal commands can be enabled or disabled
with the Internal Command Echo option. If you would like to see
TurboDLDClassic's internal commands display at the AutoCAD command line as
they are executed, enable this option.

BP Zoom Mode sets the Big Picture (BP) zoom definition area display options.
In a zoomed view of the static BP, as the ccurrent viewport is zoomed
or panned, Float mode causes the image in the BP to move around within the
bird's-eye window, keeping the zoomed viewport area fixed in the center of
the bird's-eye. Freeze mode will lockthe current BP contents into place to
provide a better overall frame of reference.

After all Expert options have been set, highlight Return To Previous Menu
and press the RETURN key to return to the Main Configuration Menu.

What If I Have Problems?
------------------------

If you encounter a problem, please review the installation
procedure and Chapter 8 - Tips, Tricks & Troubleshooting, to be sure you
haven't overlooked or skipped a step. If you still cannot resolve the
problem, refer to Appendix A to obtain Technical Support.

--------------------------------
Saving Configuration Information
--------------------------------

Once all of the TurboDLDClassic parameters have been configured, select
SAVE, EXIT to save the configuration information and create DLDSETUP.DAT,
DLXBUTTN.DAT, and DLXMENUS.DAT in the ACADR13\DOS\DRV sub-directory (R13),
ACAD\DRV sub-directory (R12) or the TURBODLD (R10/R11) sub-directory.
DLDSETUP.DAT is TurboDLDClassic's configuration file while DLXBUTTN.DAT and
DLXMENUS.DAT are the configuration files for the digitizer buttons and
pop-up menus, respectively.

After answering AutoCAD's standard driver configuration questions, you will
return back to the AutoCAD configuration menu. To begin your accelerated
AutoCAD, for AutoCAD R13, R12, select option 0, Exit to Drawing Editor; for
AutoCAD R11/10, choose option 1 or 2, Open New/Existing Drawing.


------------------------------------------
Verifying Your TurboDLDClassic Installation
------------------------------------------

To verify that TurboDLDClassic is running and installed correctly, follow
one of these two simple tests.

 If you have the AutoCAD side menu enabled, look for the Panacea Logo in
  the lower right-hand corner.

 If you are running AutoCAD without a side menu, type DLDVER at theAutoCAD
  command prompt. If TurboDLDClassic is loaded and running, this command
  should return your current version.

If TurboDLDClassic was not correctly installed, you will receive an AutoCAD
error when the DLDVER command is entered.


-----------------------------
Reconfiguring TurboDLDClassic
-----------------------------

To reconfigure TurboDLDClassic follow the instructions for AutoCAD Release
12/13 or Release 10/11 below.


AutoCAD Release 12/13
---------------------
If you need to make changes to your Release 13/12 TurboDLDClassic
configuration, type CONFIG at the AutoCAD command prompt or use ACADR13 -R
or ACADR12 -R when starting the program. Select option 3, Configure Video
Display. Answer No to the "Select a new video driver ..." prompt to start
the TurboDLDClassic configuration program. Make the desired changes to the
driver and then Save and Exit to continue to the AutoCAD drawing editor.


AutoCAD Release 10/11
---------------------
To change a Release 10/11 configuration, select option 5, Configure AutoCAD
from the AutoCAD main menu. and then from the configuration menu, select
option 3, Configure Video Display.  Answer No to the "Select a new video
driver..." prompt to start the TurboDLDClassic configuration program.
Change the desired driver options.  Save and Exit to return to the AutoCAD
configuration menu. Open or begin a new drawing.


------------------------------  TIP  ---------------------------------------
To completely reconfigure TurboDLDClassic using Panacea's defaults, delete
DLDSETUP.DAT, DLXBUTTN.DAT, and DLXMENUS.DAT from the ACADR13\DOS\DRV
sub-directory (R13) \ACAD\DRV sub-directory (R12) or the TURBODLD
sub-directory (R11/10) and then follow the Driver Configuration instructions
at the beginning of this chapter.
----------------------------------------------------------------------------



----------------------------------------------------
Configuring The AutoCAD R10/11 Operating Environment
----------------------------------------------------

During the TurboDLDClassic installation process, a ADIACAD file is
created and placed into the ACAD sub-directory. ADIACAD contains
four lines that set four separate environment variables: DLDCFG - used by
TurboDLDClassic to find all of its configuration files; and DSPADI, RCPADI,
RDPADI  - used by AutoCAD, 3D Studio and AutoShade 2 w/RenderMan,
respectively, to find the driver file. ADIACAD must be run prior to
starting AutoCAD R10 or R11 and only needs to be run once per system boot.
For automatic loading of the environment variables, ADIACAD may be
added to the AUTOEXEC.BAT file or an AutoCAD start-up batch file.

To add execution of ADIACAD to your AUTOEXEC.BAT file, insert the line

    CALL \ACAD\ADIACAD

anywhere in the file. The above example assumes that ADIACAD resides in
a sub-directory on drive D: called \ACAD.

If you don't wish to put ADIACAD in your AUTOEXEC.BAT file, you may put it
in a batch file which also starts AutoCAD, or simply remember to run the
file before starting AutoCAD. (You should also stop using any other ADI
display driver that may have come with your graphics board, since
TurboDLDClassic is a superset of that type of driver).


------------------------------  NOTE  --------------------------------------
If you get the following message:

    Out of Environment Space

when you run ADIACAD, you will need to enlarge your system's environment.
It is accomplished by adding the following line:

    SHELL=C:\COMMAND.COM /P /E:768

to your CONFIG.SYS file. The /E:768 specifies an environment size of 768
bytes. Change this number as appropriate. You will need to reboot if you
modify your CONFIG.SYS file, in order for the changes to take effect.
----------------------------------------------------------------------------



----------------------------------------
Configuring TurboDLDClassic for Rendering
----------------------------------------


To install and configure TurboDLDClassic for use with AutoCAD R13/12's AVE
Render, 3D Studio or AutoShade 2 w/RenderMan, please read Chapter 9 -
Rendering with TurboDLDClassic.



***************************
CHAPTER 3 - CHANGING COLORS
***************************


Included with TurboDLDClassic, is Panacea's revolutionary CustomColors color
configuration utility. What's so unique about CustomColors is that it gives
you the ability to modify all your changeable AutoCAD colors, including
menu colors, text colors, dialog box colors, and even drawing colors, while
running AutoCAD.

CustomColors simulates an AutoCAD screen, complete with all possible objects.
At the AutoCAD drawing editor command line, type  DLDCOLOR to edit the color
configuration.

If you have configured TurboDLDClassic for 256 colors, you will be greeted
with an informational warning message. The message appears to remind you
that if you assign a drawing color to a physical color above color 15, you
may experience unusual results from AVE Render.

Once you enter the utility, you are provided with the following
configuration menu at the bottom of the screen:

    (O)bject,
    (D)rawing,
    (P)hysical,
    (A)DI reset,
    (V)GA reset,
    (L)oad,
    (S)ave,
    (E)xit


The above menu items perform the following functions.


Object
------

Selecting this option will allow you to change the color of any AutoCAD
screen object, such as the graphics area background color, the menu area
text color, or the border line color.

Select the object whose color you want to change by moving the highlight box
around using the arrow cursor control keys and pressing ENTER when you have
highlighted the desired object. Note that a one line description of the
object type is displayed at the top of the screen as you move the box around.

Once you have selected the object, another highlight box will appear around
the color boxes nearest the bottom of the screen. These are the physical
colors that the video board supports. Use the arrow cursor keys to select
the physical color to be used for the object you have selected and press
ENTER. The screen will quickly redraw with the new color selection for the
object you have chosen, and you will be back at the start of object
selection in case you want to change the color of another object.


------------------------------  NOTE  --------------------------------------
Note that at any time during color configuration, you can press the ESC key
once or twice and return to AutoCAD. Also, pressing the question mark
("?") key will provide you with context sensitive help.
----------------------------------------------------------------------------


Drawing
-------

This 16 color configuration option allows you to modify all AutoCAD drawing
in a fashion similar to the way you change object colors.

When this option is selected, a highlight square appears in the drawing
color area of the simulated AutoCAD display. The square can be manipulated
using the four cursor keys. You may notice that the drawing color portion
of the display is laid out just like the CHROMA drawing supplied with
AutoCAD. When you press ENTER, the highlight moves down to the 16 physical
colors, just as it does during the object color selection. Using the arrow
keys, pick the physical color you want to represent the selected drawing
color. Press ENTER for your selection to take effect. When using 256 colors,
you do not have a (D)rawing Color option. All 256 colors are available as
drawing colors.


Physical
--------

Choosing the Physical option from the menu allows you to alter the red,
green and blue components of the physical colors. A highlight box will appear in
the row of 16 physical colors at the bottom of the screen.Use the arrow keys
to select the color you wish to edit and press ENTER. Three "sliders" will
appear near the bottom of the display, with the horizontal position of the
slider for each of the color components (red, green, or blue - RGB)
indicating the relative intensity of the component. You can use the left and
right arrow keys to move the slider for the selected component, or type in
a number from 0 to 255.


------------------------------  NOTE  --------------------------------------
Many graphics boards do not support 255 different intensities for each color
component. Therefore, when you enter an intensity, Custom Colors will
round it to the nearest intensity which your graphics board supports.

For example, VGAs support 64 intensities per RGB color component. This means
intensities increase in multiples of 4 (256/64), therefore an intensity
of 0 is the same as an intensity of 3.
----------------------------------------------------------------------------


The up and down arrows allow you to select which component you want to alter.
As you manipulate the sliders, all objects on the display that are of the
same color as the selected physical color will change in hue. This way you
can visually determine the most appropriate setting for your display.
Pressing ENTER will set the RGB values you have selected for the physical
color you were modifying.


ADI reset
---------

This constructs a default ADI color palette, as defined in the Autodesk
Device Interface Driver Development Kit, and in Panacea's 8514/A and
XGA non-display list drivers shipped with AutoCAD Release 13/12.


VGA reset
---------

This constructs a default VGA color palette in the first 16 color entries.
The remaining palette colors remain identical to those used for ADI devices


Load
----

This reloads the color information from the file DLDCOLOR.DAT. It will be
loaded from the directory pointed to by DLDCFG (AutoCAD R10/R11), or from
the AutoCAD R13/12 \DRV directory. If DLDCOLOR.DAT cannot be found, an error
message will be displayed.

This command is useful because it allows you to go back to your previously
edited color configuration in case you have made some mistakes in
configuring your colors that you want to undo.


==============================  CAUTION  ===================================
Don't Accidently Wipe Out Your Changes.

Selecting ADIreset, VGAreset, or Load will irrevocably wipe out any current
color changes you may have made, unless you have just saved your new
setting. So use them only when you really need to, such as when you have
made so many color changes that you can't seem to get back to a reasonable
place and just want to start over.
============================================================================


Save
----

Saves the current color palette to DLDCOLOR.DAT. It will be saved to the
directory pointed to by the DLDCFG environment variable in ADIACAD, or to
the \ACADR13\DOS\DRV (R13) or \ACAD\DRV (R12) directory if ADIACAD is not
used.


Exit
----

Exits CustomColors. If you have made palette changes, but not saved them, you
will be asked if you want to save your changes before exiting.


------------------------------  NOTE  --------------------------------------
When running at more than 8 bits-per-pixel (256 colors), setting physical
colors via DLDCOLOR will have no visible effect until a SAVE and
EXIT occurs.
----------------------------------------------------------------------------



*****************************
CHAPTER 4 - TURBODLD FEATURES
*****************************


TurboDLDClassic offers AutoCAD users many features and productivity options.
This chapter alphabetically lists the basic commands found in all TurboDLD
versions and provides the correct syntax for their usage. For a brief
summary of TurboDLDClassic commands, see Appendix B or while running AutoCAD,
type DLDHELP at the DOS prompt.


------------------------------  NOTE  --------------------------------------
Please note that the commands above with a "*" following them, when issued
within AutoCAD, will override the selections made during TurboDLDClassic
configuration, for the current drawing session only. Exiting AutoCAD and
subsequently restarting will cause all feature settings to revert back to
those selected in the TurboDLDClassic configuration menu. If you wish to
make the current changes permanent, reconfigure TurboDLDClassic by following
the reconfiguration instructions in Chapter 2.
----------------------------------------------------------------------------


The Big Picture
---------------

The most important feature of TurboDLDClassic is the support of a world view
called The Big PictureTM or just BP for short. Bringing up the BP allows
you to view where in the current drawing you are currently located in your
active viewport, and it also gives you the ability to dynamically move to
another part of the drawing without having to exit the function you're
currently executing.


DLDBIGPIC
---------

To call up the Big Picture, at the AutoCAD command line, type DLDBIGPIC, or
double click the right mouse button or button 2  on your digitizer puck
(assuming you haven't redefined your Button 2 double click function - see
Chapter 3). This will bring up the BP on the display. You will see
cross-hairs and a highlighted section indicating which part of the whole
drawing you're currently viewing - the size of the image will be determined
by the AutoCAD logical drawing space being used, 15-Bit or 31-Bit.
The selection or pick box will have an "X" through it. Move the
mouse/digitizer around to locate your pick box. If you can't see a small box
moving, click the left mouse button (the pick button) to size down the pick
area. In size mode, the pick box will have a right pointing arrow in it
("-->"). If the contents of the BP are too small to work with, you may
increase the size of the image in the window by pressing the "+" key on your
numeric keypad this performs an incremental zoom within the BP. Likewise,
pressing the "-" key will reduce the size of the contents of the BP.
Pressing the HOME and END keys will put the BP into its smallest and
largest size, respectively. The smallest BP size is defined as being exactly
the same view as that in the viewport referenced by the BP.  The largest
BP size is defined as the largest image possible without causing a Regen.

The BP pick box is always proportioned to the proper aspect ratio for the
current viewport. Clicking the pick button again will put you back into the
pick box move mode ("X"). This operation is very similar to using the Zoom
Dynamic feature of AutoCAD. Once you have positioned the pick box on the
area you would like displayed in the active viewport, click any button
other than the pick button to initiate the zoom, or press the Enter key.
If you want to abort the operation, just hold any mouse or digitizer
button down, other than the pick button, until the BP disappears. You can
also hit any key on the keyboard, other than Enter, to cancel the BP.
Note that the BP is updated with new drawing commands, but that moves or
erases will not update the image unless BPREFRESH is enabled. A DLDREFRESH
or a REGEN will manually update the BP with the current drawing changes.


DLDBPDIM
--------

Resizing and repositioning the BP can be accomplished by typing this command
at the AutoCAD prompt. DLDBPDIM allows you to tell the driver where you
want the BP placed and how large you want it to be. The size is limited to
being between one-quarter and one-half the width of the display. This
command functions like the pan/zoom selection box in the BP, as far as
positioning and dimensioning goes. To abort, hold the right mouse button,
or any other digitizer button, down until the moving box disappears.


DLDBPFREEZE
-----------

Sets the Big Picture (BP) zoom definition area display options. DLDBPFREEZE
toggles the Big Picture Zoom Mode parameter in TurboDLDClassic's Expert
Configuration Menu.

In a zoomed view of the static BP, as the current viewport is zoomed or
panned, Float mode causes the image in the BP to move around within the
bird's-eye window, keeping the zoomed viewport area fixed in the center of
the bird's-eye. Fixed mode will lock the current BP contents into place to
provide a better overall frame of reference.


DLDBPHILIGHT*
-------------

Changes the highlight used to display the Big Picture among three modes,
Patt Line, XOR Rect, and Both. Patt Lines will use dotted lines to outline
the Big Picture pick box. XOR Rect will use a contrasting rectangle to
highlight the pick box, and Both will use a combination of Patt Lines and
XOR Rect.


DLDBPMODE
---------

Toggles the Big Picture between Panning and Zooming modes. In panning mode,
the AutoCAD drawing will dynamically display the contents of the Big
Picture pick box as you size and move it. In Zoom mode, the AutoCAD
drawing remains stationary until the area in the Big Picture pick box is
accepted. At which time it changes to the chosen zoom level.


DLDBPREFRSH*
------------

This convenience feature of TurboDLDClassic, toggles the Big Picture update
mode. If disabled, the BP is updated manually by issuing a DLDREFRESH
command. When enabled, DLDBPREFRSH will cause the BP to refresh
automatically when an object is drawn or erased. The BP operations
therefore will be slower with DLDBPREFRSH enabled.


DLDBPSTATIC
-----------

Toggles the BP to stay on the screen at all times. Use this command if you
want the BP on the screen in order to conveniently move into it whenever
you want to zoom or pan. Typing  DLDBPSTATIC will put up the BP at the
position you set with DLDBPDIM. Note that the static BP will disappear
when other menus pop-up on the screen, and it will also disappear if you
draw any objects which may overwrite the BP. With these exceptions, the BP
will remain on-screen until you either exit the drawing screen or you type
DLDBPSTATIC again.


DLDCOLOR
--------

Invokes CustomColorsTM, Panacea's color configuration program. See
Chapter 4 - Configuring Colors for more information on configuring
TurboDLDClassic colors.


DLDCOMPACT
----------

Forces a manual garbage collect of Display List memory thereby returning
unused display list memory back to the AutoCAD memory pool.


DLDDIGI*
--------

This temporary command toggles the digitizer processing functions of
TurboDLDClassic on and off during the current drawing session. DLDDIGI is
included to help facilitate digitizer tablet configuration when using
AutoCAD's TABLET command.


DLDDLIST*
---------

This command toggles the display list function of TurboDLDClassic on and off.


------------------------------  NOTE  --------------------------------------
Please note that if the display list is turned off, you will be running
AutoCAD as though you were using a standard non display list driver - pans,
zooms and redraws will be MUCH slower with DLDDLIST disabled.
----------------------------------------------------------------------------


DLDECHO*
--------

Toggles internal TurboDLDClassic command echoing at the AutoCAD command line.
When TurboDLDClassic commands are executed via the digitizer or pop-up menus,
they generate internal commands which will be displayed at the AutoCAD
command line if DLDECHO is enabled. Disable DLDECHO to simplify the command
line.


DLDHELP
-------

Provides a list of TurboDLDClassic commands with one-line description of
each, within AutoCAD. It's recommended that you flip to the text
screen by pressing the <F1> key to view the output.



DLDREFRESH
----------

Refreshes the Big Picture to reflect the most current changes to a drawing.
If the static BP is up, it will be updated.  If not, the next time the BP
is brought up, it will contain a current representation of your drawing,
provided no changes were made between the DLDREFRESH command and the
DLDBIGPIC command. For Automatic update of the Big Picture, see the
DLDBPREFRSH command above.


DLDSTATUS
---------

Displays the current TurboDLDClassic status. A listing of the current
TurboDLDClassic parameters is displayed at the AutoCAD command line. A flip
to the graphics screen is recommended to view the status report.


DLDUSAGE
--------

Use DLDUSAGE if you want a to-the-byte breakdown of how memory is being
used, specifically for display list processing. DLDUSAGE returns
information regarding the memory each viewport is occupying. Since
AutoCAD supports multiple viewports, it is possible to have multiple
display lists. A new or empty drawing will have a display list of
4k bytes.


DLDVER
------

Displays the TurboDLDClassic version at the AutoCAD command line.


PD, ZD, ZW
----------

PD - Pan Dynamic, ZD - Zoom Dynamic and ZW - Zoom Window are included in
TurboDLDClassic for backwards compatibility with MACH-12. These commands
will invoke the Big Picture.


ZI, ZO
------

ZI - Zoom In and ZO - Zoom Out will zoom the current viewport in or out
incrementally.


**********************************
CHAPTER 5 - MEMORY USAGE AND LISTS
**********************************


TurboDLDClassic shares extended memory with AutoCAD via the PharLap Virtual
Memory Manager. This means that TurboDLDClassic will automatically page to
disk if it uses up all the RAM that AutoCAD has left for its use. See the
AutoCAD "Installation and Performance Guide" for more information on
Virtual Memory Management. Please note that if you start seeing excessive
hard disk accesses during PANs, REDRAWs, and ZOOMs while using AutoCAD with
TurboDLDClassic, try using the DLDCOMPACT command. If this doesn't affect
the amount of disk access it's probably time to add more memory to your
system. Contact your AutoCAD dealer for assistance in upgrading your
memory.

Regarding display list memory, it's important to realize that
TurboDLDClassic speeds up AutoCAD operations by creating a Display List in
memory, and sending that list to the graphics board for pans, zooms and
redraws. But a display list takes up memory.


----------------
How much memory?
----------------

For production use, we recommend that at least 1 megabyte is available for
TurboDLDClassic.  To determine how much memory AutoCAD is using, use the
status command while in AutoCAD (refer to the AutoCAD "Installation and
Performance Guide" for more information). The Display List for a simple
drawing like the shuttle Columbia might only require 20 Kbytes for the
Display List.  Complex drawings may require several megabytes.  We have
seen Display Lists for a drawing range from one-tenth the size of the
drawing file to three times the size; in general, the Display List averages
about one and one-half times the size of the DWG file size. This means that
you should reserve approximately two and one-half times your average DWG
file size in RAM for the drawing and the Display List.  Also, complex
objects such as circles and text "expand" when translated into display list
format, so a drawing with a lot of complex objects and text will have a
larger Display List than a simpler drawing.

If there is significant hard disk activity while you are using
TurboDLDClassic, it may be an indication that you should add more memory to
your system.


------------------------------  TIP  ---------------------------------------
Text takes up a disproportionate amount of space in the Display List.  To
keep the list small, put text in its own layer of the drawing.  Then don't
display the text layer when editing the rest of the figure.  This will keep
memory consumption down and speed up PANs, REDRAWs, and ZOOMs.
----------------------------------------------------------------------------


------------------------------  TIP  ---------------------------------------
The AutoCAD manuals have an excellent section on performance, concentrating
on memory usage.  To get the most performance out of the program, read the
appropriate sections of those manuals as well as this one.
----------------------------------------------------------------------------



********************************************
CHAPTER 6 - TIPS, TRICKS AND TROUBLESHOOTING
********************************************


Because TurboDLDClassic supports such a wide range of graphics board
platforms, it is necessary to be aware of certain idiosyncrasies. This
chapter outlines known configuration and usage problems of TurboDLDClassic
and of various graphics platforms. Also included are tips to help gain
performance from AutoCAD itself. These tips and tricks are a compilation of
the most commonly asked Technical Support questions. Therefore, if you are
having problems, please review this chapter, you may be able to quickly
answer your own question.


-----------------
Memory Management
-----------------

System lock-ups, random re-boots or missing displays, indicate you may have
a memory conflict on your system. Different video platforms access
different, specific, portions of upper memory blocks. If these memory
addresses are in use by TSRs or other programs or memory managers, the
above symptoms will occur. To avoid these problems it is necessary to use
an expanded memory manager to allocate the specific address range to the
graphics board. The address to exclude usually falls within the range of
A000 to C7FF. XGAs and some TIGAs go beyond C7FF up to DFFF.

Some common expanded memory managers are QEMM, 386MAX and EMM386 (which
comes with DOS 5.0 and later and Windows).

QEMM and EMM386 use similar commands to perform the exclusion.

    X=B000-B7FF

is added to the QEMM386.SYS or EMM386.EXE command line in the CONFIG.SYS
file. 386MAX uses a video memory parameter which look like this

    VIDMEM=B000-B7FF

Note that it may be necessary to run an optimization utility with some
memory managers in order for the exclusion to take effect. Refer to your
memory manager's documentation for specific details.

If the range of A000-C7FF seems like a large area to exclude, you may
decrease the range by changing the ending address to determine the exact
range that you need to exclude. Typically B000-B7FF, as shown in the
examples above, will be sufficient. You may try other ranges, by altering
the beginning and/or ending address, to isolate the exact region the
graphics board requires. Remember to re-boot after changing the CONFIG.SYS
file. Some common requirements are shown below.


================================  CAUTION  =================================
Due to the manner in which they re-map video BIOS memory regions in RAM,
memory optimization utilities, such as QEMM's Stealth and EMM386's
HIGHSCAN, should be avoided.
============================================================================



---------------------------
Maneuvering Through AutoCAD
---------------------------

Zooming
=======

Watch the Snap
--------------

When zooming into an image, be aware of your AutoCAD grid snap setting. If
you are zoomed extremely far into a drawing and you are having trouble
moving your digitizer cursor, you may be snapping to a  point which is not
part of the zoomed viewport. If the cursor only moves to a single point, or
is not on screen at all Snap might be turned on. Check the status bar to be
sure. If you see "Snap" listed, press the F8 key to turn it off.


Zoom $1
-------

An undocumented AutoCAD command can help speed up performance in some
situations, ZOOM $1. ZOOM $1 will allow you to set the extents of AutoCAD
Release 12's logical drawing space. by issuing the following command
sequence:

    ZOOM
    $1
    CTRL-C
    CTRL-C
    CTRL-C
    CTRL-C

The catch is that the command is only in effect until a REGEN is issued.
Be sure to zoom to the view of your drawing you wish to use as the extents
before issuing the above. If you find this command to be useful, you may
also want to try configuring for a 15-bit drawing space -- See Chapter 3 -
Installing and Configuring, "Expert Configuration" menu.


TurboDLDClassic and Paper Space
------------------------------

TurboDLDClassic features do not work in AutoCAD's Paper Space. The execution
of any TurboDLDClassic command in Paper Space, due to a limitation in
AutoCAD, will result in an error message at the DOS prompt.


Zoom Dynamic
------------

Use the Big Picture feature of TurboDLDClassic to accomplish the same task
as Zoom Dynamic, in a much more efficient fashion.


AutoCAD Release 12's CONFIG Command
-----------------------------------

Configuring TurboDLDClassic in the middle of a drawing session using the
CONFIG command is a bit like exiting and re-starting AutoCAD. If you are
using the static Big Picture and wish to resume your drawing session with it
on, issue the DLDSAVECFG command before issuing the CONFIG command.


Sticky Cursors
==============

In the Big Picture
------------------

Sometimes, when using the Big Picture, the digitizer cursor will appear to
stick to the edge of the bird's-eye. This is normal and is the result of
the digitizer puck responding to the whole screen area while the Big
Picture only occupies a small portion of the screen. Because of the
difference in resolutions between the screen and the digitizer, when the
screen cursor enters the Big Picture area, the digitizer puck has more
drawing area to cover in order to get to the same location as the screen
cursor.


Within AutoCAD
--------------

The following solutions have been used to fix slow mouse/digitizer response
problems when using TurboDLD drivers.

 Make sure that you are not using a real mode driver for your digitizer.
  Real-mode drivers do not interact properly with protected-mode drivers.
  AutoCAD Releases 10/386, 11, 12, and 13, are all protected-mode. We
  recommended that you switch to either the AutoCAD supplied driver or the
  manufacturer's latest ADI 4.2 driver for the digitizer.

 Make sure that no digitizer key re-assigning TSR's are being used. Some
  digitizers, specifically the Kurta IS/One, use TSR's to allow digitizer
  programming; these will not work with TurboDLD.

 Try deleting all files with a .DAT extension from your TurboDLD sub-
  directory and re-configuring TurboDLD from scratch. Occasionally, these
  .DAT files can be corrupted or updated improperly during installation or
  reconfiguration.

 Try the DLDDIGI command to see if the problem goes away when TurboDLD's
  digitizer processing function is disabled.

 Try changing the double-click interval time to 5 or 10. This can be
  adjusted from the User Interface Menu of TurboDLD.

 If a specific digitizer key is causing a problem, use the Delete key to
  remove any AutoCAD commands from that button. Button programming commands
  are in the User Interface menu within the Button Configuration Menu. Be
  sure to use the Delete key, not Spaces to remove existing commands.

 Depending on the digitizer you are using and how it is configured, try
  adjusting CFIG386's -VSCAN parameter. Check the AutoCAD "Interface,
  Installation and Performance Guide"  for specific instructions on how to
  use CFIG386.

 Try using the CFIG386 -DEMANDLOAD ON setting for AutoCAD.

 If there is one available, try to duplicate the problem with a second
  mouse or digitizer, this will help to isolate the cause of the problem.

 If your digitizer is capable of it, try configuring for SummaSketch
  emulation and use the driver included with AutoCAD.

 If there is a choice in your digitizer's configuration, try configuring
  it for Polled vs. Interrupt driven, or vice versa.


Using AutoCAD Commands
----------------------

Since TurboDLDClassic is totally transparent to users with respect to using
normal AutoCAD commands to REDRAW, PAN, and ZOOM, you still have to suffer
from some of AutoCAD's nuances. One of these nuances is that ZOOM ALL and
ZOOM EXTENTS both force a REGEN, because AutoCAD does not keep track of
various boundaries necessary to avoid the REGENs. And REGENs are rather
time-consuming and don't use any display list processing to speed
themselves up. One way around this problem is to use another of AutoCAD's
built-in features, namely the VIEW command.

When you first load your image and see the whole drawing on the screen at
once, just type VIEW Save ALL, which will save the display position you see
under a view named "All". Then, after you've done some detailed editing and
want to return back to the big picture, type VIEW Restore ALL, instead of
ZOOM All or ZOOM Extents, and the full drawing will be restored to the
display at display list speeds, without a REGEN.

Another nuance of AutoCAD's is that if you zoom in too far or pan over too
far, you may inadvertently cause a REGEN. AutoCAD again provides a very
simple solution: the REGENAUTO command. Just type REGENAUTO Off at the
AutoCAD command prompt, and automatic REGENs will be disabled. The
REGENAUTO setting is also saved as part of your drawing file, so you only
need to execute it once per drawing. You may even want to set REGENAUTO off
in your ACAD.DWG drawing template so that all your drawings are created
with REGENAUTO set off.



--------------------
Third-Party Software
--------------------

If you are having trouble with TurboDLDClassic and third-party AutoCAD
applications, be sure that the third-party application supports ADI 4.2. In
order to use the ADI 4.2 specification, third-party applications require
new T-Drivers and therefore must be revised. If an application does not
specifically say that it is ADI 4.2 compatible, it probably is not. Check
with the manufacturer to be sure.

If your third-party application is ADI 4.2 compatible and you are having
trouble using TurboDLDClassic, try running AutoCAD without the third-party
application to try to isolate the problem. Also, try the third-party
application with the SVADI driver shipped with AutoCAD, this will also help
to isolate the source of the problem.

Also note that any third-party TSR that needs to access the display may not
work properly when using AutoCAD with any advanced ADI display driver,
especially if the TSR switches graphics modes. Most TSRs will not support
the same graphics platforms as TurboDLDClassic and therefore, will not be
able to accommodate mode switching back and forth.


--------------
Slow Scrolling
--------------

If you have configured for the graphics mode text window and are
experiencing slow script file execution, it might be your graphics board.
Some graphics boards do not handle graphics mode text scrolling very
quickly. To test this, try configuring for the SINGLE screen option in the
Basic Configuration sub-menu of the TurboDLDClassic Configuration menu.


--------------------
Color Considerations
--------------------

Switching Color Modes
---------------------

When switching color modes, (i.e. from 16 to 256 or vice versa) the
DLDCOLOR command should be run in order to reconfigure your color palette
for the number of colors selected.


Changing to a Light Background
------------------------------

If you would like to switch from TurboDLDClassic's default black background
to a white or light background, type

    DLDCOLOR

at the DOS prompt to start the CustomColors utility. Once there, press O
for (O)bject and then move the highlight to the Background item and then
press ENTER. Move the color highlight to the desired new background color
and press ENTER. Next, move the highlight to the Cursor item and press
ENTER. Move the color highlight to the desired new Cursor color and press
ENTER. Press the ESC key and then S to (S)ave and E to (E)xit. You should
now have a light background with a dark crosshair.


----------------------------------
Corrupt TurboDLDClassic Data Files
----------------------------------

If you are having problems configuring TurboDLDClassic, be sure that you are
using either the original distribution diskettes or a faithful copy made
with the DOS DISKCOPY command. We have at times received Tech calls where
we could not trace a specific recurring problem which later turned out to
be a bad duplicate disk.

If everything appears to have installed correctly and you still can't seem
to figure out what's happening, try deleting the DLDSETUP.DAT, DLXMENUS.DAT
and DLXBUTTN.DAT files from your TurboDLDClassic sub-directory. You'll then
have to reconfigure the driver from scratch.  We've seen some strange
things happen when these files have become corrupted.


--------------------------------------------
Configuring TurboDLD for Your Graphics Board
--------------------------------------------

You may need to look for your graphics board by its video chip instead. In
these cases, you must configure for mach64. Check your documentation,
or if you already know it, use the Generic selection for your chip type.


-------------------------
Static BP in Panning Mode
-------------------------

When using the static Big Picture in panning mode, the drawing screen will
continue to pan until you move the cursor out of the Big Picture viewport.
The drawing screen will display the selected view correctly.



Locating the Correct ACAD.CFG File
----------------------------------

You must use extreme care to locate the proper ACAD.CFG version. On
networked systems, systems with the SHARE utility installed, and on systems
with third-party add-on software, the ACAD.CFG file may not be in the
default AutoCAD directory. There may be several copies of ACAD.CFG, and
they may be in several different drives and directories. ACAD.CFG may be
write protected. On some networks it may not be accessible from your system
for reading or writing.  The following steps can be used to locate the
proper ACAD.CFG file.

1. You may need to examine the environment variables PATH and ACADCFG, and
   the ACAD directory, to find the proper copy of ACAD.CFG. One way to verify
   that the proper copy was found, is to type the following DOS command

    DIR ACAD.CFG

2. You can then compare the date and time of the file with the date and
   time you last exited from AutoCAD. Each time you exit from AutoCAD, the
   ACAD.CFG file date and time is updated. Thus the date and time should
   change when you enter and then exit from AutoCAD.

3. Another way to verify that you found the proper ACAD.CFG file is to
   temporarily rename it. At the DOS prompt type:

       RENAME ACAD.CFG ACADCFG

   then try to run AutoCAD. If it runs as usual, then you have not renamed
   the proper copy of the ACAD.CFG file. If you receive the message,
   "AutoCAD is not yet configured",  then you know that you are working with
   the right copy. Type CTRL-C a few times to get out of the AutoCAD
   configuration menu. You can now copy TURBO.CFG using the command

       COPY TURBODLD.CFG ACAD.CFG

4. If you are experiencing difficulties after you modified the original
   ACAD.CFG, you can delete the ACAD.CFG file, enter AutoCAD, and reconfigure.

CHAPTER 7 - Autodesk 3D Studio and Autoshade
********************************************

Installing the Driver for 3D Studio
-----------------------------------

1.  Insert the install disk in floppy drive A: or B:.

2.  At the DOS prompt, type a:\install or b:\install, depending on the drive
    selected.

3.  From the menu, select the 3DStudio option.

4.  The following options are available, select one:
    Install 3D Studio Ver 1, 2
    Install 3D Studio Ver 3
    Install 3D Studio Ver 4

    The default installation directory for 3D Studio 1, 2 is \3DS.
    The default installation directory for 3D Studio 3 is \3DS3.
    The default installation directory for 3D Studio 4 is \3DS4.

    The required files are copied to the appropriate sub-directory.

5.  Exit the install program and proceed to configuring 3D Studio to use
    the TurboDLDClassic driver.

Since TurboDLDClassic is a combined, display and rendering, device driver,
it can be used to generate high-resolution renderings with Autodesk's 3D
Studio and AutoShade programs, as well as with AutoCAD R12's built-in AVE
Render. Configuration for these programs basically involves selecting the
proper Display and Rendering resolutions from the TurboDLDClassic
configuration menu. The other driver configuration options, except for font
selection options for 3D Studio, are ignored for rendering because a
Display List, and its configuration parameters, is not used during the
rendering process.



----------------------------------------------------
Selecting the Driver for use with Autodesk 3D Studio
----------------------------------------------------


3D Studio Versions 1.0 and 2.0
------------------------------

1.  Set the environment variables for 3D Studio by running the ADI3DS.BAT
    file that was copied into your 3D Studio sub-directory.

2.  Delete (or rename) the 3DADI.CFG file from your 3D Studio sub-directory
    by typing: DEL 3DADI.CFG

    Deleting this file will cause 3D Studio to start in its reconfiguration
    mode. 3DADI.CFG will be recreated after 3D Studio has been reconfigured.

3.  Edit the 3DS.SET file located in your 3DS directory.

    The following three lines of the 3DS.SET file tell 3D Studio which driver
    to use for the rendering screen, main screen and materiald editor screen,
    respectively. Locate the lines that begin with:

    RENDER-DISPLAY
    MAIN-DISPLAY
    MATERIAL-DISPLAY

    and change them to use the RCPADI driver as follows:

    RENDER-DISPLAY=RCPADI
    MAIN-DISPLAY=RCPADI
    MATERIAL-DISPLAY=RCPADI

    Make sure to remove the ";" or any spaces that may be present at the
    beginning of the line.

4.  Start the 3D Studio reconfiguration by typing: 3DS.

5.  Proceed to Configuring the TurboDLD driver.


------------------------------  NOTE  --------------------------------------
For 3D Studio 1.x, there is no RENDER-DISPLAY line. The corresponding line
is DEFAULT-DISPLAY and should be changed to read

    DEFAULT-DISPLAY="RCPADI"

The quotes around RCPADI must be used for this version of 3D Studio.
----------------------------------------------------------------------------



3D Studio Version 3.0
---------------------

1.  Set the environment variables for 3D Studio by running the ADI3DS.BAT
    file that was copied into your 3D Studio sub-directory.

2.  Delete (or rename) the 3DADI.CFG file from your 3D Studio sub-directory
    by typing: DEL 3DADI.CFG

    Deleting this file will cause 3D Studio to start in its reconfiguration
    mode. 3DADI.CFG will be recreated after 3D Studio has been reconfigured.

3.  Use the Autodesk supplied utility to edit the 3DS.SET file. From your 3DS
    sub-directory, type: 3DS VIBCFG to display the configuration screen.

    Use the TAB key to move the cursor among the available parameters. The
    ENTER key allows you to select an available driver. Change the
    RENDER-DISPLAY, MAIN-DISPLAY and MATERIAL-DISPLAY fields to use RCPADI
    and then press SHIFT-TAB to move to OK. Press ENTER and save your changes.

4.  3D Studio will automatically be loaded now.

5.  Proceed to Configuring the TurboDLD driver.


3D Studio Versions 4.0
----------------------

1.  Set the environment variables for 3D Studio by running the ADI3DS.BAT
    file that was copied into your 3D Studio sub-directory.

2.  Delete (or rename) the 3DADI.CFG file from your 3D Studio sub-directory
    by typing: DEL 3DADI.CFG

    Deleting this file will cause 3D Studio to start in its reconfiguration
    mode. 3DADI.CFG will be recreated after 3D Studio has been reconfigured.

3.  Use the Autodesk supplied utility to edit the 3DS.SET file. From your 3DS
    sub-directory, type: 3DS VIBCFG to display the configuration screen.

    Use the TAB key to move the cursor among the available parameters. The
    ENTER key allows you to select an available driver. Change the
    RENDER-DISPLAY, MAIN-DISPLAY and MATERIAL-DISPLAY fields to use RCPADI
    and then press SHIFT-TAB to move to OK. Press ENTER and save your changes.

4.  3D Studio will automatically be loaded now.

5.  Proceed to Configuring the TurboDLD driver.


------------------------------  NOTE  --------------------------------------
Note that it is only necessary for the RENDER-DISPLAY line to be set to
RCPADI in order to render at high resolution. If you do not need a high
resolution main display screen or if you will not be using the materials
editor, you may keep MAIN-DISPLAY and MATERIAL-DISPLAY set to their
defaults.
----------------------------------------------------------------------------



================================  CAUTION  =================================
The MATERIAL-DISPLAY should only be configured for RCPADI when BOTH the
Display AND Rendering Resolutions of TurboDLDClassic are configured for 256
color resolutions. An unpredictable Materials Editor screen will appear if
anything other than 256 colors is selected. If you are unsure about the
function of the Materials Editor screen, use the Materials Editor as VGA,
you should not have any problems at all. Please note too, that the use of
the Materials Editor will not give you any more colors to choose from, just
higher resolution.
============================================================================


Configuring TurboDLDClassic for use with 3D Studio
--------------------------------------------------

During the 3D Studio start-up, you are prompted with a series of
configuration questions. After each question is answered, TurboDLDClassic
will display either its Display or Rendering Configuration menu. will
appear with either a Display.

To configure the 3D Studio Main Display for your graphics board, from the
Display Configuration menu, select a display graphics board and then a
display resolution.

To configure 3D Studio for the Rendering and/or Materials screens, select a
rendering graphics board (usually the same as the Display board) and a
rendering resolution. (For detailed information on choosing graphics boards
or display and rendering resolutions, See Chapter 2 - Installing and
Configuring.)

Because RCPADI device drivers, by definition, are combined Display and
Rendering devices, during 3D Studio reconfiguration, you may be brought to
the TurboDLDClassic Configuration Menu more than one time each, each for
Display and Rendering. It is not necessary to select display and/or
rendering resolutions a second time. Simply press the ENTER key to remove
the help screen and then highlight Save and Exit to continue to the next
question. When ADIACAD.BAT is used to define the AutoCAD operating
environment, the TurboDLDClassic Configuration Menu will also appear
for RDPADI and DSPADI devices if they are present.


------------------------------  NOTE  --------------------------------------
Some 3D Studio Limitations:

TurboDLDClassic only provides still rendering support for 3D Studio. This
driver will not play back rendered FLI or FLC files at resolutions above
the 320x200 default of 3D Studio.

If you have a VESA compatible graphics board you may be able to use the
RCPVESA.EXP driver that comes with 3D Studio to display animations at high
resolution. Refer to your 3D Studio Installation and Performance Guide for
specific information.
----------------------------------------------------------------------------



----------------------
Configuring AVE Render
----------------------

AutoCAD 13/12's AVE Render uses TurboDLDClassic's rendering capabilities to
render objects and drawings. If AVE Render has never been configured, when
you select the AutoCAD render command, you are required to run through its
configuration process. In this case, you are prompted through the following
questions and/or menus.

1. Select a Rendering Display device. Since TurboDLDClassic is a combined
   display/rendering device, choose item 1,  P386 ADI Combined
   Display/Rendering Driver from the available choices.

2. Configure the Rendering Graphics Board and Resolution. Here the
   TurboDLDClassic configuration program will appear on the screen. Press the
   Return key to continue past the help screen and display the Rendering
   Configuration menu. Choose Select Graphics Board/Resolution to display
   graphics board and resolution menu selections. Select a rendering graphics
   board and then a rendering resolution.

3. Select Render Mode. The next step is to select the rendering mode for
   TurboDLDClassic. Select either Render to Viewport or Render to Screen
   depending on how you wish to view your renderings. Note that in order to
   render to a viewport you must be using a Display resolution of more than
   16 colors. Otherwise, AVE Render will not allow the render to viewport
   selection.

4. Select Render Hard Copy Device. If you are using a rendering hard copy
   device select your device type from the list of choices. If you are not
   using a hard copy device, accept the default of NULL.

After configuring AVE Render, you will return to the drawing to render the
current drawing.

If you have previously configured AVE Render for another driver, you will
need to reconfigure. Type RCONFIG at the AutoCAD command prompt to manually
invoke the Render Configuration Menu. Follow these steps to re-configure
AVE Render.

1. Select option 2, Configure Rendering Device to choose a new rendering
   driver. Answer Yes to the "Select Different Rendering Device" question.

2. Select option 1, P386 Combined Display/Rendering Driver to choose the
   type of driver being used.

3. Configure the Rendering Graphics Board and Resolution. At this point,
   the TurboDLDClassic configuration program will appear on the screen. Press
   the Return key to continue past the help screen and display the Rendering
   Configuration menu. Choose Select Graphics Board/Resolution to display
   graphics board and resolution menu selections. Select a rendering graphics
   board and then a rendering resolution.

4. Select Render Mode. The next step is to select the rendering mode for
   TurboDLDClassic. Select either Render to Viewport or Render to Screen
   depending on how you wish to view your renderings. Note that in order to
   render to a viewport you must be using a Display resolution of at least
   256 colors. Otherwise, AVE Render will not allow a render to viewport
   selection.

5. Select Exit to the Drawing Editor from the Render Configuration menu and
   then type Y to keep the changes you've just made. Press the <F1> key to
   change to the graphics screen if necessary.



--------------
AutoShade v2.0
--------------

Installing the Driver for AutoShade
-----------------------------------

1.  Insert the install disk in floppy drive A: or B:.

2.  At the DOS prompt, type a:\install or b:\install, depending on the drive
    selected.

3.  From the menu, select the AutoShade option.

    The default installation directory for AutoShade is \Shade. The required
    files are copied to this sub-directory.

5.  Exit the install program and proceed to configuring AutoShade to use
    the TurboDLDClassic driver.


Since TurboDLDClassic is a combined, display and rendering, device driver,
it can be used to generate high-resolution renderings with Autodesk's 3D
Studio and AutoShade programs, as well as with AutoCAD R12's built-in AVE
Render. Configuration for these programs basically involves selecting the
proper Display and Rendering resolutions from the TurboDLDClassic
configuration menu. The other driver configuration options, except for font
selection options for 3D Studio, are ignored for rendering because a
Display List, and its configuration parameters, is not used during the
rendering process.


------------------------------------------------------
Configuring the TurboDLD Driver for use with AutoShade
------------------------------------------------------

To configure AutoShade v2.0 to use TurboDLDClassic, first run the
ADIACAD file from your TurboDLDClassic sub-directory to set the
AutoShade environment variables. Next, start AutoShade with SHADE /R, which
will allow you to reconfigure AutoShade. For the display device, select
P386 Autodesk Device Interface display driver, and for the rendering
display select the P386 Autodesk Device Interface rendering driver. If you
are running the display and rendering screen on the same monitor (i.e.
single monitor), make sure to tell AutoShade this. A single monitor
approach will require a redraw of the display screen after a rendering
screen.

Once the P386 ADI devices have been selected, the TurboDLDClassic
configuration menu will be displayed.Follow the same installation steps
that were used to select the graphics board and display and rendering
resolutions for AutoCAD (see Chapter 3 - Installing and Configuring).



*********************************
APPENDIX A - Troubleshooting Tips
*********************************


If you experience any problems, please complete the PANACEA.TXT problem
reporting form.

Many of the problems which may occur in setting up and using TurboDLDClassic
are not really problems with the driver; instead, the problems occur in
installing and getting access to additional memory for the driver.

Memory management programs, such as  QEMM, 386MAX, and EMM386, can cause
memory conflicts on certain graphics platforms. In order to avoid these
conflicts, it may be necessary to exclude certain memory regions from being
used by the memory manager.

Also, if you are using a memory manager, avoid using any switches or
utilities of the manager that may re-map upper memory blocks in order to
load as many programs and TSR's "high" as possible (i.e. QEMM's "Stealth"
mode or EMM386's HIGHSCAN). These features can make it difficult or
impossible for TurboDLDClassic utility programs to locate certain video
BIOS information. If you have memory problems, carefully check both the
system documentation and the memory manager documentation before contacting
Technical Support. System memory problems probably won't be solvable by us.

We aren't able to fix mis-set jumpers and incorrect configuration options
over the phone. Please be sure that all hardware is installed and operating
correctly before assuming that the driver is at fault. Carefully check your
hardware documentation for the correct switch and jumper settings.
