The Autodesk Revit user interface comprises several screens, panels, and toolbars that facilitate project organization. For example, the Project Browser has places for structural plans, 3D views, and elevations. The Project Browser also contains more complicated aspects of Building Information Modeling (BIM) that include legends, schedules, quantities, and sheets. Revit software’s UI also has a Quick Access toolbar at the very top of the ribbon, a status bar in the lower-left corner, visibility controls, and a comment area that shows you where you are in the model.
