Pro/E Sleight of hand : switch drawing models

Joe Slow has duplicated a complex assembly, made changes, replaced parts, etc... but when they come to edit the drawing they realise they forgot to include it in the duplication process! (Or they somehow duplicated the drawing, but left it pointing to the old assembly.) How can they have a copy of the "donor" drawing referring to their new assembly?? They consider re-drawing from scratch, but there's got to be an easier way, right?

Right indeed. I tend to use a little sleight of hand to swap the drawing models when Pro/E is not looking (I'll assume Joe is using Intralink, since that's the hardest case):

1. Open the "donor" drawing (or wrong-pointing drawing) + assembly from workspace
2. Unhook Pro/E from Intralink for a moment (Tools > Server Registry > Set NO SERVER, Don't erase)

3. Rename the donor assembly to the new assembly while the drawing is in session.
4. File > Backup the Drawing to disk
5. Erase everything from memory
6. Hook-up with Intralink again (reverse previous process)
7. Open New assembly from workspace
8. Open Backup drawing from disk
9. Save drawing to Workspace (overwrite warning)

Image tries to explain process visually...

(If you're not using Intralink, ignore the unhook + hook-up steps.)

So now Joe Slow has a nice new drawing relating to the new assembly, and you get a pat on the back! This trick depends on duplication between the old + new (I don't think you could replace any old assembly this way), plus Pro/E can only deal with one file of a particular name... so when you open the backup drawing from disk, it sees the new assembly already in session and uses that instead of retrieving the old assembly from disk.
