I'm modifying the DWF Eplot.PC3 that came with AutoCAD 2000i. There are alot of sheets sizes that we don't use, so i went to filter them out. But when i go to modify margins of existing sheets, the whole list of sheets show up. It seems the whole filtering / margin thing is quirky. I would modify a margin. and save it.. and my filtered sheet list would not be filtered anymore.. the whole list of sheets would show up again. Is there a correct and incorrect procedure to do this? Modify margins first then filter? Or the other way? Seems like sometimes it keeps the filtered sheet list and sometimes it doesn't. Comments?
