I made a small lisp that runs about 300-400 Boolean operations on a very very complex solid.
During AutoCAD processing it creates a "UNDB595A.ac$" file inside the Windows TEMP folder with huge dimensions (30-40 GB !!).
To remedy this, I thought to temporarily disable the UNDO command and then rehabilitate it at the end of the process.
Unfortunately UNDOCTL is a read-only variable
Do you have any advice for doing this?
Thanks in advance
