I had a look around, and couldn't find anything on this. Here's the problem: I have some assembly drawings with indented BOMs. In some of these drawings, when I collapse a subassembly or weldment, the rows are blanked instead of hidden. In one of these drawings, I was not even able to manually hide the rows. The drawings with this problem seem to be larger than the others. That's the only pattern I see so far.
Has anybody else seen this? Any suggestions?
