I have a subassembly assembled into the main assembly. I want to modify its offset mate so as to reposition the subassembly in the top assembly. Move it just a little further in one direction. When I go to modify the dim and do a view mate and pick the particular constraint the whole subassembly disappears and does not cdome back until I exit out of view mates. How do I get the sub to stay visible while I modify the mate and watch the sub dynamically move as I edit the dim that i want?
