Are you saying you want say a A3 sheet 420x297 but with 3 viewports, that can be done. To have a oversize sheet does not make sense to me. You just set up the sheet details and the location of each viewport, not hard to do.
("A3" "0,20" "140,190" "140,20" ""280,190" and so on)
Hi Steven, spot on! The LISP definitely flags raw geometry changes, not design intent.
I actually use it as a "first pass" safety net. It's much faster to let the script cloud everything that moved and simply delete the few "false positives" (like lines stretched for spacing) than to manually hunt for actual design changes.
For the overlapping issue: the clouds are standard polylines on a dedicated layer. You can easily grip-stretch them out of the way, or use DFCT beforehand to increase the padding so they draw looser.
It doesn't replace a drafter's eye, but it definitely handles the heavy lifting of finding the changes first! Thanks for checking it out.
