I was working on a model, when I went to zoom in very close on a small naked edge, the Perspective Viewport stopped responding. When I went back to 4 viewports and select something and Zoom selected for all 4 viewports, the Ortho views all respond as expected, but the Perspective viewport shows nothing (in wire display mode, ghosted, rendered) and I get this:
“Unable to zoom some views - no objects are selected.”
I tried copying and pasting the contents and if I tried the whole file, the new file had the same problem. If I copied and pasted only selected items that new file seemed to be fine. The file is almost a Gig, so I don’t know if that is/was a factor, it’s just weird because because the rest of the file all seems to work fine, no issues, just the perspective viewport. Even if I go to “set view” as change to Top, Right, etc. that one viewport just doesn’t do anything. I can change the other viewports to perspective and that works, but in 4 viewport mode, the top right square is just dead/blank/grey like it would look like with no geometry.
