We are a medium scale office transitioning from Autocad/Sketchup/3Dmax to Revit. While the documentation is going OK we are having issues convincing people to use Revit at the initial design phase for massing, sketch models and 3D schematic presentations. They say Revit can produce the same results as easily as something like Sketchup. Is it worth pursuing Revit as a beginning to end program? If so what are the key tips to convince new users?
