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).
...banging on the keyboard isn't helping.
If you type the command "UNDO", the command line should show options associated with the command. You can limit the amount of commands that UNDO will store, or temporarily disable it altogether.
