-
- The shareware concept has made it possible for you to obtain extremely
- powerful software at a price you can afford, and it gives you the
- opportunity to try the software before you register.
-
- Shareware is kept alive by YOUR support.
-
- Evaluate the program for 30-days and give copies to your friends for
- evaluation. If, after the 30 days, you continue to use the program,
- then register it by sending us the registration/order form included in
- this help file or by calling 800-468-7487 (Orders Only!). You will
- receive the Latest version, Printed manual, 90-day free Technical
- Phone Support, BBS Technical Support, Newsletter, and Reduced price
- Upgrades.
-
- In addition to that, the 'UNREGISTERED COPY' message will be
- eliminated from the screen and a tool bar with the most frequently
- used commands will take its place. Registering will also get you the
- capability of using external script files to create series of TGA and
- PCX files for animation sequences. And, of course, it will get you the
- legal license to use the software beyond the 30-day evaluation period.

-
-
- GETTING STARTED
- ~~~~~~~~~~~~~~~
- The information provided below is to help you start the program for
- your hardware configuration. For more details about the operation of
- the program press the F1 (function) key once you have started the
- program.
-
- Once installed (see below for installation procedure) ProtoCAD 3D is
- started from DOS using the command:
-
- C:> PC3D /Option1/Option2/Option3/..... [ENTER]
-
- where Option1, Option2, etc. are options specifying the type of
- memory to use, the type of graphics video adaptor, etc. For a
- complete description of these options, please print and consult the
- on-disk user's manual.
-
-
- Ordering Information
- ~~~~~~~~~~~~~~~~~~~~
- Remember that a shareware copy is an EVALUATION copy that you can use
- for up to 30 days. If you continue to use the program, Registration
- and payment are Required! You may register using the order form in the
- ORDER.ME file, or by calling TRIUS, Inc. and charging your purchase on
- your credit card. We suggest that you call, since prices are subject to

- can save you the delay and inconvenience which may be involved in
- dealing with currency conversions and international shipping and in
- many cases will provide you with faster technical support.

- Files on the ProtoCAD 3D Distribution Disk(s)
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- PC3D20.FLS - Compressed Archive
- READ.ME - Start-Up instructions (This file)
- ORDER.ME - Ready-to-print order form
- LICENSE.DOC - Please Read This!!
- VENDOR.DOC - Info on Distributing Shareware Copies
- INSTALL.EXE - Automated SetUp File
-
-
- Installation on Floppy or Hard Disk:
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- The program will work if installed on 3.5" (720K or 1.44Mb) diskettes,
- or 5.25" HD (1.2 Mb) diskettes. We recommend that the program is
- installed either on a hard disk, or a high density floppy diskette,
- since this will permit the help file, and other auxiliary files, to be
- available to the user.
-
- If you Install and run ProtoCAD 3D from a floppy disk, without
- Expanded memory (EMS), or if the /NE command line switch is
- used, and you remove the ProtoCAD 3D program disk from
- the drive while the program is running, you will get an
- error message and will be instructed to re-insert the disk.
-
- * Place the ProtoCAD 3D original diskette in drive A: (or B:)
-
- * Make sure the current logged drive is A: (Type A:, or B:, and
- press ENTER, if it is not).
-
- * Type INSTALL and press [ENTER]. Then, follow the simple on-screen
- instructions to install your copy of the program on the desired disk(s)
- and/or subdirectory.
-
-
- Upgrading from Ver 1.1 or earlier
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- If you are upgrading from an earlier version of the program, we
- recommend that you install the program in the directory where the old
- version resides, answering Yes when the installation program asks if
- you want to overwrite the files. Furthermore, it is recomended that
- you delete the old configuration file (PC3D.CFG), in that directory
- prior to running ProtoCAD 3D v2.00.
-
-
- Windows Users
- ~~~~~~~~~~~~~
- ProtoCAD will work fine under Windows 3.1. If you are going to run the
- program in a windows environment, you may use the files PC3D.PIF and
- PC3D.ICO which are extracted as part of the installation process. It
- should be noted that the PC3D.PIF file is setup to run the program in a
- windowed mode. For better program response, however, we recommend that
- the PIF file is modified (using the Windows PIF Editor), to run in full
- screen mode.
-
-
- On-Disk Documentation
- ~~~~~~~~~~~~~~~~~~~~~
- The installation process extracts a file called PC3D.MAN. This is a
- ready-to-print formatted, User's manual for the program.
-
- Following the installation, make sure that the PC3D.MAN file is
- indeed on your default directory. Then, to print this manual:
-
- (1) Make sure that the your printer is ON and there is enough
- paper in it (the manual is about 100 pages).
-
- (2) From the DOS prompt, type
-
- COPY PC3D.MAN PRN and press [ENTER]
-
- Note that if your printer is connected to a SERIAL port,
- then you need to use the command COPY PC3D.MAN COM1, or
- COPY PC3D.MAN COM2 (depending on which serial port your
- printer is connected to).
-
-
-
- NOTES/ADDITIONS TO THE USER'S MANUAL
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- 1. When a new view is selected, an image extents scan is made and the
- image is placed in the center of the screen (similar to performing
- an Image, All command), if the Auto Ctr toggle is ON.
-
- 2. Identifying reference marks are placed in the center of facets. This
- is particularly useful when trying to change the surface normal, since
- it permits you to select uniquely identified facets.
-
- 3. The limit on the number of points that can be accommodated when
- importing a WAV file, was increased to 8000.
-
- 4. VGA 256-color and VESA color mapping is done using a 3,3,2 model,
- i.e., 3 bits are used for Green, 3 for Red and 2 for Blue. Since
- there is not enough resolution (2 bits) for Blue, you might
- experience blue patches when rendering an 'almost' gray scale image.
- If that happens, select the Gray option in the Render sub-menu.
-
- 5. When rendering in 256 colors, the edges are NOT visible regardless of
- the setting selected in the Render, Edges sub-menu.
-
- 6. The trackball employs an effective 'gimbal lock' mechanism. If the
- image is rotated/rolled beyond a 90 degree angle, the Yaw angle
- automatically switches by 180 degrees.
-
- 7. As the observer distance (D) is reduced, and you move closer to the
- center of the image, you will observe some clipping of polygons that
- are effectively behind the focal length plane. This normally occurs at
- about D=0.5. You might need to render the image to re-orient
- yourself.
-
- 8. When attempting to print without EMS, the 32k-48k shadow buffer is
- used by the Z-buffer model to internally render the image in
- horizontal strips. Since the buffer size is limited, the longer the
- strip (specified print width) the narrower the vertical strip size
- that can be accommodated. When the calculated vertical size falls
- below 16 scan lines, the program will not render and will abort the
- printing process. This limit will accommodate a 7.5 inch width at
- 120 dots per inch resolution. Under these conditions, if you want to
- increase the resolution, you'd have to reduce the specified print
- width. For above example, if you wanted to use 240 dpi resolution,
- the specified width should be approximately 3.75 inches.
-
- 9. When creating TGA output files, the program requires approximately
- 300k of EMS to render the image. If it's not available, the TGA
- output menu is disabled and an appropriate error message will be
- issued.
