This has been happening to me for a few months now and it's getting crazy.
I maintain a system that converts 2D blocks to their corresponding 3D blocks on our network. It's an old but very reliable. The problem I'm now having is using the 3D model as a reference for the 2d wireframe (actually in 3d but is nothing but lines and arcs).
I have been exploding the 3D models down to lines and cleaning them up but when I re-block them they have started retaining the original file size.
I've tried all the usual suspects.
-there are no hidden blocks in the drawing.
-it's thoroughly purged
-tried saving as every kind of file imaginable opening and re-saving.
I'm talking about a file that started out a 500k but should be down to 50k when I'm done but there is no difference in the final size.
using 2002
any help would be greatly appreciated
