Thanks in advance. 1. Please refresh my memory about how to search past postings on a subject or keyword. If I could remember I would have searched first, but here goes: 2. How do I use viewmode = 1 to invoke 3Dpan in the acad.mnu. The goal would be to get the wheel to pan, whether the view was 3D perspective or not. Perhaps a (while (viewmode = 1) (and then something about MBUTTONPAN, perhaps?) but how would this work in the acad.mnu portion that defines mouse AUX buttons? If not possible using the wheel, any thoughts about using the right button? Thanks again, John Cole
