I haven't used the Reference Viewer for some time but I am trying to track down a circular reference. I have watched several videos that go through the process and all have a "Paths" tab in the Reference Viewer which I do not have. Did something change in Creo 4.0 or earlier that got rid of the Paths tab?
Re: Creo 4.0 Reference Viewer - Paths tab is there.
I usually use the .crc text file that creo generates in the working directory. So in the one below, the problem is in the middle segment "extrude_1, id=470)". It's always the middle one but you can sometimes solve the problem by correcting assembly constraints.
