I have a drawing with a viewport drawn with MVIEW. It is just a rectangle-wasn't built with the polygonal option or anything. I have another viewport, drawn the same way, which I want to layer over the first. I want this second viewport to block out whatever it overlaps from the first. Is this possible? If so, how? I realize I could draw a polygonal viewport to replace the first but I am curious to know if this can be done. Also, along the same lines, is it possible to edit the viewport if it was not made from an object or polygon/polyline. I have had no luck with those that were just drawn as a box at the prompt though all the others are editable. Any help is much appreciated.
