Having a weird issue here when I copy/paste drafts views from one draft file to another. The first copy/paste action I make works fine. The second group of views (from the same source file or another one) I try to copy/paste just doesn't work at all. Furthermore, the action won't work in the source file either. I first believed there was some kind of clipboard saturation keeping me from doing my task. I have tried clearing up the clipboard in windows but that didn't help as far as I am concerned. I have rebooted my desktop but didn't get any results either when opening up the new draft file again.
The problem seems to occur when dealing with older files though. The one I'm dealing with seems to come from version 18.104.22.168.
I have tried to replicate the same scenario with recent files and everything works fine.
Sounds like a file specific issue, that your VAR, or if you have access, "GTAC" could help with. Very hard to say what could be the cause without eyeballing the file....perhaps parent/child model links need to be repaired. Are there any indicator brackets on the model views? Not that this should stop the copy/paste action.
Out of interest, what Solid Edge version [and MP] are you using, and on what OS?
