So I preformed an operation (quadremesh) and every object (curves, subds, mesh, surfs) in the perspective viewport disappeared. Still able to do Selall and I can view normally in iso views. I played around with the tumbling and viewing and discovered that viewport acts as the the clipping edge on the camera is turned super up. so lets say the camera were to zoom in to 5ish mm from the surface I can see my geometry.
I do use a 3dconnexion spacemouse and am running on a quadro graphics card.
I have reset camera, saved as, exported objects, imported objects from fresh document, all without any changes.
unable to load the file, its 40mb.
