You'll notice right away that Revit's interior elevations look more like sections. We use a No Pattern Filled Region to crop the extents of our interior elevations. This comes in handy since crop regions can not yet be shaped the way a filled region can.
Very often sub grade basements will show in elevation when no topography model is present. Again we use a No Pattern Filled Region to "crop out" the basement walls. If you want to hide an edge of the filled region just edit the filled region and change the boundary line to Invisible lines
