Configuring TurboDLD
Classic
, cont'd
Expert Configuration Menu
This menu customizes of the driver or adjusts for memory
constraints.
Menu Item Description
Display List Enables the display list feature. This option should always be
enabled. Disabling it causes TurboDLD
Classic to run as an
ordinary non-display list driver.
Drawing Cache Enables the drawing cache, a compressed list of the current
viewport, which speeds pans zooms and redraws. The Drawing
Cache should normally be enabled. Disable it if not enough
memory is available. Disabling drawing cache frees memory
for AutoCAD but may not have effect zooms and pans.
AutoCAD Logical
Drawing Space
Configures TurboDLD Classic for AutoCAD R12 31-Bit
logical drawing space when set to Yes . Select No to use a
15-Bit drawing space. The 31-Bit logical space allows you to
extend the Regenless zooming ability by a factor of several
million while using more memory. Additional memory is used
by AutoCAD for drawing space and by the driver for the
Display List. 31-Bit zooming and panning is 10% to 20%
slower than for 15-Bit logical space.
Use AutoCAD 31-Bit
Space is ignored for AutoCAD R11.
Internal
Command Echo
Enable this option to display internal commands at the
AutoCAD command line as they are executed.
Big Picture Zoom
Mode
Sets the Big Picture (BP) zoom definition area display options.
WHen using a zoomed view of the static BP, the image in the
BP move in the bird's eye window as the current viewport is
zoomed or panned, keeping the zoomed viewport area fixed in
the center in Float mode. Freeze mode locks the current BP
contents for a better frame of reference.
Regen Mode Fast Regen stores the AutoCAD drawing until the Display List
has been created and then display it. Incremental mode
displays the drawing in chunks as the display list is created.
Fast mode processes 5% to 10% faster than the incremental.
Neither mode changes memory requirements.
