%(#800080)[Hi G;
Yes, I do believe there's some mystery geometry in my specific model that causes the freeze. My workaround has been to do the SAVEAS, and then in the copied file delete, not hide, absoulutely everything that wont' appear in the 2d section cut. It's a bit of a bear, but at least I don't have to redraw in ACAD, right?
At the least, the Forum has helped me confirm that I'm not missing any basic knowledge, and the various feedbacks have led to my workaround.
much appreesh!
