We have a number of assemblies where we make a part for each piece of base material, then assemble them. Picture two plates assembled in a tee. The plate components have no links from anything. Then we create a component in-place and use the edges of the plates to extrude a weld volume.
Next, we add an assembly cut feature to trim some of the weld and base machining away. Circular references appear. (?!?!)
The CRC does not appear if I go to the extra effort of making another assembly that contains the post-weld machining cut features, but to go back and do that on older subassemblies is a nightmare.
I don't remember that happening in the past, and in my mind it's not a CRC, and there is nothing harmful about this practice. Regeneration is sequential according to the feature tree in the assembly:
1) Assemble plate 1 2) Assemble plate 2 3) Assemble weld to default coordinate system a) Regenerate weld feature using plate 1 and plate 2 references 4) Regenerate assembly cutIf this was always the case feel free to slap me in the head. But if it's a bug or change I'll submit it to PTC.
