I am not new to Solidworks, but I have limited experience with Design Tables. I have an Assembly with 20 configurations and I want to put 19 of these configs as derived under 1 that has commonality with all. It was suggested several times to me, this could be accomplished in the Design table. After many youtube vids, and several attempts to manipulate, copy and paste, nothing seems to be working. What can I do/am I doing wrong?
