My pipe network has become entirely disconnected, the pipes are no longer attached to the structures. The pipes will not reattach to the structure by draging it over a structure. Reviewing the pipe vista all the begining and ending structures are missing. The pipes and structures are still in the drawing with the correct data. However, you can not reattach the pipes to the structures. I can draw new pipes and attach to the existing structures no problem. I can use the attach part command with the structure and pipe, and the pipe snaps to the center of the structure, however, the pipe does not connect to the structure.
The above happen after I audited and purged the drawing.
Anybody know how to fix this?
