I have a custom command that creates a derived part of a component occurrence selected from an assembly. It has worked well for years, but there are two similar part files that one of my external modeling resources created that fails to create a "DerivedPartUniformScaleDef" by code. I can manually create a derived part as a user, so I'm not sure what is going on with it.
I have attached a pack n go of a testing assembly with the block of code containing the derived part creation where the error occurs. The assembly contains the two bad parts and one known good part for testing purposes [see model browser folders].
Any insight would be helpful.
