OK, I found the External References Palette. However, when I see the saved path and it is wrong, the status says not found. I have not found a way to select the correct path. I can detach and then attach the drawing again, but that messes up the multiple instances of insertion of the notes and other occurrences in the drawing set. Any ideas?
