size of the drawing file to three times the size; in general, the Display List averages about the same
as the DWG file size. This means that you should count on the Display List taking up as much as
twice the DWG file size. 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 has a larger Display List than a
simpler drawing.
Keeping the Display List Small
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. Do not display the text layer when editing the rest of the figure. This
keeps memory consumption down and speed up PANs, REDRAWs, and ZOOMs.
Read the AutoCAD Manuals
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.
Tips and Tricks
This section includes the topics "Upgrading From Older Panacea DLD Drivers" and "Maneuvering
Through AutoCAD." These topics provide tips and tricks for using TurboDLDClassic
more
successfully.
Upgrading From Older Panacea DLD Drivers
Be sure to remove any reference to previous DLD driver commands (FASTACAD calls or SET
parameters) or sub-directories that may be in your AUTOEXEC.BAT file or in AutoCAD start-up batch
files. Such references could cause AutoCAD and TurboDLDClassic to look in the wrong place for
setup information.
If you have been using a previous Panacea DLD driver and wish to use the color palette you
customized for it with TurboDLDClassic, you may copy the DLDCOLOR.DAT file from your older
DLD's sub-directory to the sub-directory you specified during the TurboDLDClassic installation
process.
Maneuvering Through AutoCAD
Zooming
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 that is not part of the zoomed viewport. If the cursor only moves to a single point,
or is not on screen at all, turn the grid snap off.
TurboDLDClassic and Paper Space
TurboDLDClassic features do not work in AutoCAD's Paper Space. The execution of any
TurboDLDClassic command in Paper Space results in an error message at the command prompt.
Zoom Dynamic
We do not recommended using ANY TurboDLDClassic features while in the Zoom Dynamic mode of
AutoCAD. Because TurboDLDClassic cannot determine when Zoom Dynamic has been initiated,
