I uninstalled Revit 13 and reinstalled it. It still doesn't act right. When I zoom in close, it loses responsiveness. It won't pan or anything when zoomed in.
I talked to a local puter person; he didn't know. He suggested 2 more rams wouldn't do much. He also wondered if my grafics weren't strong enough. Would grefics not being strorn enough cause the problems I am having?
