Introduction
============
This text file, "ReadMe!", contains last minute updates and other
useful and important information. See the file called "Revisions"
on disk 4 for additions and bug fixes to DynaCADD since 3.00.00.
o CLI/Shell users need to use Stack 30000 before running DynaCADD.
o Keyboard menu alternates use either [Alt] or [Amiga] key with the
respective letter.
o In order for the menus to drop down the mouse pointer needs to be
in the menu bar area, otherwise the right-mouse button is used by
DynaCADD for command completion or cancelation.
o The Install utility can also be used to update DynaCADD in
your system. Simply run Install and specify the destination.
Install will copy only the files that have changed. This means
that when you copy DynaCADD files, make sure that you use the
CLONE option with the CLI/Shell Copy command.
Additions to 3.00
=================
********************** IMPORTANT *************************
**** Please convert all your old files into DEF format ****
**** in order to transfer them into this new version!! ****
************************************************************
1. The 3-D math has been rewritten using improved algorithms.
As such, old 3-D planar entities converted over using DEF 2.0
may be improperly rotated. We do apologize for this but felt
it was preferable to change now than at a future date, given
the sudden rise in the use of the 3-D mode. To properly align
the GCPs, DEF in the part from the previous version and save it
out. Now create a new 3-D part, merge in the previous part
and recreate your views.
2. A new entity type (3-D Face/Solid) has been added. All
appropriate selection and transformation commands have
been upgraded to work with the new entity type. Plotting,
Printing and PostScript output have also been upgraded.
3. Entity Snap: End has been updated to allow snapping to
2-D solid corners and 3-D face corners.
4. Once selected, an entity may be deselected by clicking
the mouse button while the entity selection cursor is
positioned on the entity and the [Shift] key is held down.
5. Hidden line removal has been added. The command icon is
found in the EDITVIEW sub icon pad. Clicking on the
HIDEFACE command will remove the hidden lines from all
selected views.
A new Hidden Line Parameters dialog has been added
to the Set menu.
The options are:
Generate Entities:
Create 2-D lines from the edges of the 3-D Faces after
the hidden portions of the edges have been removed. The
entities are created with the following attributes:
Layer: Active
Weight: #1
Style: Continuous
Color: If inheritance is active the line is
created using the color of the face,
otherwise the active color is used.
Display Entities:
Will display all other entities after the hidden lines
have been generated.
Blended Planes:
If two or more Faces share a common edge and the two
Faces are coplanar, the edge will be removed and the
two Faces blended into one. Note that only the hidden
line is changed, the defining entities remain
unmodified.
Hide Views 1-2-3-4:
Only selected views will have hidden lines removed.
6. DXF import has been upgraded to include the layer color
and style information. A new color transformation dialog
appears during a DXF import requesting the color
transformation preferred. The various transformations
available are:
Dark: Sets color palette to AutoCAD dark background.
Light: Sets color palette to AutoCAD light background,
None: No palette transformation.
In order to set the colors properly without distorting the
colors of the DynaCADD interface, a color translation table
is employed. If no color index translation is desired, use
the "None" option on the transformation dialog.
7. The DXF in translator has been enhanced and improved.
These improvements include:
- Support for 2 1/2-D entities.
- Support for 3-D entities.
- Proper evaluation of $Flatland header variable for 2 1/2-D.
- Proper evalulation of $Fillmode header variable for Trace entities.
- Elevations are supported.
- 3-D Extrusion using 3-D Faces is supported.
- All six AutoCAD text justification modes are supported.
- UCS Tables are converted to DynaCADD GCP's.
- Polyline line bulge factors are now converted to DynaCADD Arcs.
- Translator upgraded to AutoCAD Release 10.
- Insert Block repeat counts are supported.
8. The DXF out translator has also been enhanced and improved.
These improves include:
- Upgraded to compatibility with AutoCAD Release 10
- More detailed DXF Header file.
- Passing of 3-D UCS Table mapped from DynaCADD GCP Table.
- Layer color and style have been added to the Layer Table.
- Bspline and Bézier curve are interpolated using spline fitting.
9. A DXF out 3-D option has been added. When DXF out 3-D has
been selected, all DynaCADD 3-D entities, including the new
3-D face, will be output. Planar entities such as arcs and
text have their coordinate planes converted from DynaCADD
GCP to AutoCAD UCS.
10. DEF export has been upgraded to version 4.00. A quick
summary of enhancements include:
Global Variables:
Version
ColorByLayer
StyleByLayer
WeightByLayer
Mask
Unmask
Viewmask
3-D View Tables
Color Tables
GCP Tables
Image Tables
Layer Tables have been extended to include color, weight
and style information.
Layer Tables output unnamed layers.
Bsplines and Béziers no longer add an extraneous point.
Note: The inclusion of the Version global in DEF 3.00+
files is mandatory and is now required for the
proper importation of DEF.
11. DEF 3.00 documention is in a file called DEF300 in the
DynaCADD drawer on disk "DynaCADD 4".
12. A color PostScript option has been added to the
PostScript parameters dialog. When this button is
selected, color information for each entity is included in
the PostScript file, otherwise a monochromatic file is
generated.
13. A page counter has been added to the set PostScript
parameters dialog. The number of pages (1..99) is
displayed in the page size area of the dialog.
14. When trying to exit DynaCADD or cancel background output,
a dialog has been added requesting confirmation.
15. Inserting figures now uses the inheritance flag to
determine the color and layer information the figure will
use. If inheritance is turned on, the figure will have the
same color and layer as the parent figure had when it was
created, otherwise the figure will be inserted on the
currently active layer using the current color.
16. A new Layer Attributes dialog has been added to provide
quicker access to all layering information. The dialog
is accessed through the Layer menu item found under
the Set menu title.
17. Color, Style and Weight By Layer toggles have been added
in the layer icon pad. When these switches are turned on,
entities are drawn in the color/style/weight associated
with the entity's layer, otherwise the entity is drawn
using the color/style/weight with which it was created.
Plotting, Printing and PostScript routines have also been
modified to work with the new flags.
18. A Transform: Copy icon has been placed in the top icon bar
The icon and help message toggle with the state of the global
flag. Duplicate entities are created when Transform: Copy is
active, while only one set of entities is shown on the icon
when the flag is deactivated. The command to toggle the
Transform: Copy flag is TRANCOPY.
19. The maximum number of rotation copies has been
increased from 360 to 3600.
20. The maximum number of revolution copies has been
increased from 360 to 3600.
21. Coordinate tracking has been extended from 5 to 6 digits
on the left side of the decimal providing a tracking
range of +/- 999999.99999.
22. The TRIMINTOF command has been changed to TRIMCORNR.
The functionality remains the same.
23. A new command TRIMINTOF has been added. This command is
functionally identical to Trim Corner with one exception.
The second entity selected is used only to determine the
intersection location and is not trimmed or modified in
any manner.
24. The POINTFILE command has been moved from under the
CREATE icon submenu to the OUTPUT icon submenu.
25. The Translate command has had an icon submenu added to
it with 3 entries. Move, Copy and Copy Multiple. The
Transform: Copy flag is no longer evaluated for
translations.
26. The TRANMOVE command functions identical to the
TRANSLATE command with the Transform: Copy flag disabled.
27. The TRANCOPY command functions identical to the
TRANSLATE command with the Transform: Copy flag enabled.
28. The TRANMCOPY flag is similar to the TRANCOPY command
except the original entities selected to be copied are not
deselected once the translation is performed. The first
translation location (the "from" location) is retained.
To deselect the current group of entities, press the right
mouse button before selecting the second translation
location (the "to" location).
29. The TRANSLATE command now has a Translate with 3-D Faces
option. When the 3-D Faces options (found under the
TRANSLATE icon) is selected, all Translated entities are
joined with 3-D Faces. Faces are created only when copies
are done.
30. The PROJECT command now has a Project with 3-D Faces
option. When the 3-D Faces options (found under the
PROJECT icon) is selected, all projected entities are
joined with 3-D Faces, otherwise projection lines are used.
31. The PROJECT command now honours the "inheritance" flag
when constructing projection lines or 3-D Faces.
32. The REVOLVE command now has a Revolve with 3-D Faces
option. When the 3-D Faces options (found under the
REVOLVE icon) is selected, all revolved entities are
joined with 3-D Faces.
33. The SWEEP command now has a Sweep with 3-D Faces option.
When the 3-D Faces options (found under the SWEEP icon) is
selected, all swept entities are joined with 3-D Faces.
34. A new dialog showing the last active part and drawing
has replaced the old AutoStart dialog. In addition, an
"Exit" button has been added. This button will exit
DynaCADD and return you to the WorkBench.
35. For users of the Calcomp PCI and 907 format drivers the
following settings must be active on the plotter's
intelligent controller:
Sync char: 1 sync char = 2
End of Message: 13
Checksum: disabled
Flow Control: XON/XOFF
Note: The Calcomp 907 format plotter must be using an
intelligent controller or rotation of a plot will
generate a plotter logic error.
Serial port configurations for most plot drivers
are as follows:
8 bits / character
Stop bit(s): 1
Parity: None
Baud: computer and plotter must match
Flow Control: XON/XOFF
Exception: Users of the Calcomp 960 Extended driver
must set Flow Control to RTS/CTS
36. 3-D Text can be revolved, swept, projected and copied to
create 3-D Faces.
37. Export of 3-D Faces to rendering packages has been added to
the File Transfer dialog. Imagine, Sculpt, LightWave and
VideoScape are currently supported.
3-D Faces are converted to triangles for Imagine and Sculpt.
Grouped Faces are maintained as an object in Imagine files.
If rendering of an object in LightWave does not quite come
out the way it should, check for surface normals pointing
in the proper direction.
38. And minor bug fixes and enhancements too numerous to list...

Set buttons in Pen Indexes Dialog
The "Set" buttons are only active during TRANSFORM MODIFY CHAPEN.
They enable selective transformation of pen color, line weight, or
line style depending on their selected states. For example, if the
Set buttons beside pen color and line weight are selected, only the
color and weight attributes will be changed while retaining the
previous line style.
New UNDO Capabilities
You can now UNDO layer, pen color, line style and line weight
changes, as well as other TRANSFORM MODIFY commands.
Command History
It is possible to clear the command history buffer. Press the
[Del] key while the Command History window is visible.

Bug Reports
===========
We have tested DynaCADD 3.00 and its functions very thoroughly,
although it is impossible, in this kind of application, to cover all
possibilities. In the event that you discover functions that are not
working as they should, please advise us as soon as possible.
When you call or write, please give as much detail as possible and
the steps that led to the problem. This will greatly assist our
development team in tracking down and fixing any remaining oversights.
Bug reports and any other feedback can also be sent electronically
via CompuServe, GEnie and BIX to the following accounts:
