I create a solid block, then I create another solid to extrude from the first block. I go to dimension the second solid to constrain it. I dimension X successfully, then I go to dimension Y and the dimension function will not work. The system bumps me out of dimension. I then have to select dimension again. The same thing happens when I try to mate two parts in XY & Z. After selecting two faces to mate it drops out of the mate function and I have to start all over. Is there something new in 2020 settings?
Thanks so much in advance, Rich
