My 3D default view now shows nothing! I have a large project that has worked fine until recently. The camera shots still work and all my drawings are in tact, I just cannot look at my building in 3D orbit any more because the screen is blank. Tried ZA, Zoom to fit, nothing hidden. Any ideas?
Solved! Go to Solution.
Fixed it! After I went to View Graphics and turned off the imported CAD links from a metal building supplier I could see my Revit model! I have had this problem once before when I was tracing a CAD file (DWG) with Revit and then could not see section cuts because apparently the CAD had some 3D to its own file that was blocking Revit. After I turned off the CAD file I could see the Revit. Did not try deleting the default 3D viewport, but it may have worked. Hope this helps others. Anyone ever had this happen to them?
