I've a 1500 part assembly made up of 77 unique sub-assy's which are made from 480 unique parts, etc. Basic big machine stuff, I guess.
I made the assy in 2001+sp6, it's about 26Mb after doing a couple SaveAs's to try to shrink it a bit. In 2K1+ it would not create a drawing view without automatically hiding random parts.
After cursing a while I found that I could dig down the Tree to the offending hidden part right which I could find only by looking for the 'bounding box' on the screen as all the Icons in the Tree showed all parts to be visible. I'd right click the part, selest Show Part, SWX would do its magic and the part would show.
This would also cause the other previously "hidden" parts Icons to change to show me they were indeed Hidden. So I could dig thru the others and do the same to get all the parts to show.
When we switched to 2003, I could create a complete drawing and I all was good...until this morning when I created another view, some parts of some sub-assys were hidden, I was able to 'recover' the parts as described above, but it sure is a PITA.
Anyone ever seen anything like this? Could it be video card related?
