AutoCAD Logical Drawing Space
Using AutoCAD 31-Bit Space, this option configures TurboDLD
Classic for use with
AutoCAD R12's 31-bit logical drawing space. When set to Yes, the driver uses
AutoCAD's extended 31-bit drawing space. Selecting No uses a 15-bit drawing space,
similar to that of AutoCAD R11.
The 31-bit logical space allows you to extend your Regen-less zooming ability by a
factor of several million at the cost of more memory. Additional memory is used by
AutoCAD for the drawing space, and by TurboDLD
Classic for the Display List. 31-bit
zooming and panning is about 10%-20% slower than for 15-bit logical space. The Use
AutoCAD 31-Bit Space setting is ignored for AutoCAD R11 installations.
Internal Command Echo
The echo of TurboDLD
Classic internal commands is enabled or disabled with the
Internal Command Echo option. If you would like to see TurboDLD
Classic's internal
commands display at the AutoCAD command line as they are executed, enable this
option.
Big Picture Zoom Mode
Sets the BP zoom definition area display options. In a zoomed view of the static BP, as
the current viewport is zoomed or panned:
•
Float mode causes the image in the BP to move around within the bird's-eye
window, keeping the zoomed viewport area fixed in the center of the bird's-eye.
•
Freeze mode locks the current BP contents into place to provide a better overall
frame of reference.
Regen Mode
•
Fast Regen mode stores the AutoCAD drawing until the Display List is created, and
then displays it, all at once.
•
Incremental mode displays the drawing in "chunks" as the display list is created. The
Fast mode causes Regens to process approximately 5%-10% faster than the
incremental.
Neither mode changes memory requirements.
After All Options Have Been Set
1. Use the arrow keys to scroll down to the Save and Exit option and then press the
[Enter]
key to continue.
2. Configure the AutoCAD screen display characteristics and type
[Y]
to accept the
changes.
