Hi all, I am trying to figure out how to associate or relate certain dimensions on two different part with one common feature so that if you change one it will automatically change both? For example I have two parts which look completely different, size, length,height and everything but the I.D. is the exact same and they both mate to the same part. Say we change the size of the part that mates to those two, how can I get it so I can just revise the inside of one part and have it do the other automatically?
