Hello community! Thank you for responding to my queries and doubts. Currently I am working on defining relations between parts in assembly mode for automating the assembly. My question is, after creating a code in pro/program by creating equations in relations and providing input statements, after executing the code when I try to save the assembly, a prompt appears saying part models have not yet regenerated. So I went to each part and made sure the parts regenerated. Do we need to do this for every instance of assembly and for each part? Because if hundreds of components are present then I think this task might get cumbersome. Please correct me because if we use lookup_inst function, can we avoid going down to each part/sub assembly to regenerate them?
