So far I have been using it for a project where we are only doing a 15% design. The scope of the project is to create a basic floor plan, elevations, 2 section cuts, and a roof plan. It is a 18,000 sf dinning facility. So far Revit has been awesome for that. I am a bit apprehensive about using Revit on projects where we have fine detailing or things like beams penetrating through walls, but I suppose I will cross those bridges when I get there.
