Ive got an assembly of a skeleton model and a number of sheetmetal parts that make use of this skeleton.
I dont know since when but something went wrong and if I cant edit any of the sheetmetal parts, I only get to see the following error in the message area:
OHNO! This is all the information provided.. I cant edit the external merge, I cant edit anything. The skeleton is still there. How can I find out what reference part is missing? I tried: Tools --> Model intent --> Program --> Show Design. But I dont see anything out of order.
Please (PTC) Help 
!
