I'm using SW 2018 SP 4.0. We switched to this version at work a month or two ago. Since then, I've noticed something haven't seen before. I made a hole in a part using the hole wizard, and then, on a drawing, called out the hole as a hole, and added a tolerance. I then went back into the part file and opened up the hole, changed nothing, and closed it. When I went back to the drawing, the tolerance had disappeared. I did this multiple times on multiple computers all using the same SW version and got the same results. If I create the same hole as a cutout, there's no problem. If I call out the hole diameter with a standard smart dimension, there's no problem. Does anyone know what's going on?
