I have an assembly model that contains a configuration. The configuration just suppresses all but a few parts of the model. I created a drawing for my assembly. On the drawing, one of my views is of the configuration mentioned above. When I try to save the drawing, I get the error message shown in the attachment. I click OK, and it pops up 2 more times. The drawing saves, but when I switch back to my model to save it, I get the same error message (only one time) and it won’t save. Once I open the drawing, I can’t save any changes to my model. So if I need to make changes to my model with the drawing open, I’m out of luck. I have to close everything and re-open the model only to make my changes, then open the drawing and update it. If I remove the drawing view with the configuration, everything saves without any issues. So it seems the drawing view of the configuration is the problem. Any ideas?
