I am attempting to make new assemblies which have similar parts as other assemblies I have already made. I bring one assembly into another and delete the components I dont. I then use the remaining part of the assembly to make the new assembly. I then check the new assembly back into the PDM Workgroup vault. When I check the new assembly back out to work on it the parts that I had previously deleted are there again. Does anyon know of a way I can permanently delete certain parts of a sub assembly?
