Constantly getting this message with one particular drawing:
"Warning! Undo has been disabled in order to prevent undo file overflow. You may re-enable it via the undo command. The undo file length was 1857669610 bytes"
What exactly does this mean? How can I remedy?
Using a 64-bit install, the drawing has imported .shp files and a georefenced DOI (x-ref'd)... doing some prelim road design work. AutoCAD generally crashes on me with this particular drawing (~1.65 M in size).
