Documentation Addendum
(Vellum 2.12 Windows Version)
Vars / Technical Support / Registered Users
This literature is for your own information based upon design
and documentation issues pertaining to Windows 2.12.
Hopefully these issues will clarify some of the questions Vars,
Technical Support, and Registered Users may be asking. These
findings have been gathered by Ashlar's Development team to
communicate a better understanding of this exciting new
product!
___________________________________________________
--Angular Dimensions--
Angular dimensions will display all angles properly if you keep
the angles larger than 3 degrees. For angles smaller then that,
you should build the dimensions manually using lines and text
objects.
--Arrow at End/Arrow at Start--
To update arrowheads when you change the text size, the next
time you "click" on the screen the change will automatically be
updated. You also can change arrowhead size in Edit Objects.
--Arc Length Dimensions--
The Arc Length dimension tool does not put the witness lines
perpendicular to the arc for angles less then 180 degrees.
--Arc Length Values--
To specify the diameter for an arc created with the connected
line tool, press and drag the arc to its approximate position.
Then select the arc and use Edit>Edit Objects to enter and
apply a diameter value.
--Ashlar Plotter Driver--
To install the Ashlar Plotter Driver you must bring up the
Control Panel's Printers Dialog. If you have "Ashlar Vellum
Plotter" on your list of installed printers, select it and click
the "remove" button. Then click "yes" when is asks if you are
sure. Then click the "Add" button. A "list of printers" list box
will come up. Select the line that says: "Install Unlisted or
Updated Printer". Click the "Install" button. A new dialog
titled "Install Driver" will come up. Insert disk #1 in your
floppy drive. If your install drive is B:, type "B:" in the
dialog in place of the "A:\". Hit the "OK" button. You can then
set it to the default printer if you want. Hit the "close"
button to dismiss the dialog.
--Ashlar Plot Settings--
The following are the recommended settings for Ashlar Plot:
[Control Panel/Printers
- Ashlar Plot on COM1 (or the port to which your plotter is
attached)
- Use Print Manager
[Control Panel/Printers/"CONNECT" Button
- Transmission Retry set to 600
- Turn on Fast Printing Direct To Port
[Control Panel/Printer/"CONNECT"/"SETTINGS" Button
- Baud Rate = 9600
- Data Bits = 8
- Parity = None
- Stop Bits = 1
- Flow Control = XON/XOFF
--Bitmaps--
Keep the scale of Bitmaps at 1:1 to generate good visual
imagery. Expanding or shrinking Bitmaps will distort geometry.
--Crosshair Points--
Double clicking on the same point with a geometry creation tool
(such as the line or circle tool) will create a zero-length
object. These zero-length objects are represented by small
crosshairs. You can select and delete them if desired. NOTE:
These crosshairs will print/plot as single dots.
--Detail Views--
a) When exporting to DXF, IGS, etc., only the currently
selected view will be exported. If no views are active (the
sheet is active), only the sheet and geometry on it will be
exported--no geometry in any of the detail views will be
exported. If one of the views is selected, only the geometry in
it will be exported--none of the geometry in other views or on
the sheet will show up. (DXF, IGS, etc., cannot understand
"views")
b) Text, dimensions and crosshatching will not associate
between detail views. They will only appear in the view in which
they were created. This is by design, and also very necessary.
--Edit Objects for Layers--
To move an object to a different layer, use edit objects.
Select the geometry, choose Edit>Edit Objects, and use the
Layer pull-down menu to make the change. Then use "apply" to
make the change take effect on the geometry.
--Ellipses--
Ellipses do not have center points by design. If you draw lines
between opposite "vertex" points on the ellipse, then the
intersection of the two lines will be the center of the ellipse.
For a two-point ellipse (inscribed in a rectangle) the drafting
assistant's horizontal and vertical temporary construction
lines will cross at the center point once you have touched two
vertex points.
--Fillet--
The fillet tool puts a tangent arc between any two objects.
Smart walls must be "un-grouped" before fillet trimming can
occur.
--Flatten Views--
Overlapping or identical co-linear lines of the same weight and
color will be converted to a single line as a result of the
flatten view command. Overlapping identical arcs, circles,
ellipses, and splines will not.
--Fonts--
Ashlar Plot can accurately plot any Windows stroke font.
Other fonts use the plotter's built-in hardware font.
--Grid--
Setting Grid preferences will cause a show grid automatically.
--Grouping--
The color of a group can be changed. This change has no effect
on the included geometry. When the geometry is ungrouped, each
piece will become its original color again.
--Interrupting a long Operation--
Long operations such as a redraw or linear or polar duplicate
can be interrupted by hitting the ESC or BREAK key. If the
operation was initiated by a control key command (such as
Ctrl-R for redraw) the ESC key is read by MS-Windows and it
brings up a task list at the end of the operation. For this
reason the BREAK key is the recommended way to interrupt a long
operation.
--Locked Endpoints on Splines--
"Locked points" on a spline only work for control points other
than endpoints. Endpoints will unlock themselves after any
changes are made to the spline.
--Locked Objects--
To edit a locked object, you will need to unlock it. Select the
object, then choose Arrange>Unlock. You are then free to edit
the object.
--Multiple Sheets--
When importing documents with multiple sheets, all geometry
from the imported document is put in the current view (usually
the current sheet).
--Ordinate Tools--
To use ordinate vertical and horizontal dimension tools, select
the beginning reference point at .000 <click once> and then
click each additional dimension location. To get the origin
(.000) dimension, you must first click a different dimension
point, then come back and click a second time at the origin.
--Parametrics/Resolve--
The Edit>Resolve dialog box will always have five entry boxes,
even when fewer or no parameters are defined. If there are more
than five entries, the box will have a scroll bar to allow
access to the rest. Also, in the Resolve dialog the Enter key
moves the cursor through the boxes, so you must choose OK with
the mouse.
--Polygons--
Use the entry boxes marked "D" and "Sides" at the bottom of
your screen to change any polygon when first creating it. After
that, it becomes a series of separate line objects.
--Preferences/Selection--
If you want your selection to be blinking and Windows is set for
16 (or more) colors, you must change it each time you start
Vellum. To do so, choose Layout>Preferences>Selection... and
select "blinking" as your choice for indicating selected
objects.
--Selection Mask--
After it has been closed, the selection mask will be reset by
changing or re-selecting any tool or changing sheets.
--Smart Walls--
Geometry trimmed to both sides of a smart wall will leave a
segment in the wall.
--Splines--
You cannot move both endpoints of the same spline at the same
time. You must select and move the endpoints individually.
--Spline Intersections--
If you create a spline that crosses over itself, the drafting
assistant will not be able to find that intersection. This is by
design.
--Symbols--
If moving symbols onto a smart wall, be sure to grab the
symbol's "wall" line endpoint and snap to top or bottom of the
smart wall; then the symbol will mask properly.
--Width & Height--
You cannot change the Width and Height of a rectangle in Edit
Objects. You must edit each line individually, because rectangles
become 4 line objects after you deselect the rectangle.
--Precision Display--
In a Vellum document, all values (dimension, length, and
tolerances) will be displayed based on the current precision
settings. For example: the tolerance value .027 will be
displayed as follows:
Precision Settings Displayed Value
.1 .0
.01 .03
.001 .027
.0001 .0270
--Layout>Preferences>Units--
This precision setting will be reflected in all data fields
within Vellum (in edit objects, the status line, and all dialog
boxes). This precision setting does not affect the display of
digits in dimension objects. The precision of dimensions can be
set in Dimension>Linear.
--Tolerance in 2D Analysis--
For 2D Analysis, the tolerance field is used only during
calculations, not for output.
