I think I need the VPCLIP command. I have a large viewport and I want smaller additional viewports on top of it. What I don't want is what is in the "behind" vport showing through the "front" viewport. A quick search online returned the VPCLIP command, which appears to be what I need. I'm not sure, since that command does not appear to be enabled in the embedded AutoCAD that comes with the standalone Survey 2010?
Any thoughts or ideas?
