So I’ve been using SU for several years and have never had this issue. Please see the attached photo. When I Zoom it starts showing the interior of the model prematurely, to the point that I can’t even edit in the center of the screen.
Found the problem! Was deleting things to take the size down and removed the Geo-Location and that seems to have fixed it. So for anyone troubleshooting this try removing your Geo-Location if you have it.
Not while modeling. I was using it to checking shadows bot I can toggle it as needed. I shrank the map fairly small and it was still causing some clipping so I just turned it off.
