Hi Matthijs,
To use either of the routine successfully some certain rules should be followed. Speaking of P&G - here they are:
1. Place copied files in the location away from your work Project file. So the Inventor can't see them. Desktop is fairly common place for that.
2. Make the Project file created by P&G current.
3. Open the upper level copied assembly and make sure there is no unresolved files in it. Rectify if necessary.
4. Close the assembly and open it in Design Assistant. Rename all the files in there. It will preserve all the links in copied assembly.
5. Check the renamed assembly in Inventor again. If no issue reported - copy the folder into the directory which your work project is looking into.
6. Change the project file in Inventor to the one you normally use.
7. After making sure all new files are behaving properly - you can delete the folder from your Desktop.
When dealing with P&G tool don't forget to select associated drawings as well. It is overlooked often enough, BTW. The IDW files can although be renamed in DA. But frankly - it takes so much time to get them open by the DA that more often than not I just rename them manually. By doing so one should be careful and know what he/she is doing, of course.
All pro all - it is quite doable. But it is certainly not a one click away business.
Cheers,
Igor.
