I am relatively new to routing....I have one assembly drawing that when I create a connection point in tubing, electrical or piping the Selections section for type of route has "fabricated pipe" grayed out slightly and cannot be changed.  It only happens in one assembly drawing.  Other drawings I can change it to tube etc.  I checked the routing subassembly: and it shows Pipe_1-Filename.sldasm.  No such file exists?  Tried changing that and didn't help...
