I have no idea. Try settting everything to be visible. Model view options, renovation filters, 3D filters, layer settings, partial structure. Set a dark line marquee around everything and view in 3d. Remove cut planes ( not an issue here, but a good idea in general for diagnosing on screen problems).
Once eveything is either ON or visible, etc, you might discover the problem.
[EDIT] Ah.. Just noticed you are working in Project Map. You must work from saved views in the View Map. Otherwise what you see on screen will change all the time.
In Project Map view, when you change a setting, it is not permanent. So let's say you set all layers to be visible in your (project view) plan, then you click on your generic perspective, and .. boom .. , all your settings got changed to the perspective settings, anything you changed in plan view is lost. So that is why it is so important to work in saved views from the View Map
