The ability to generate multiple views - including both 2D & 3d drawings, as well as BIM models which are linked together with our CAD model in Revit or Navisworks was great! There is nothing that I dislike about this program at all except perhaps its learning curve (which can be overcome!). Having an integrated tool for creating documentation from start to finish makes it easy not only to create documents but also communicate effectively across teams/departments within my organization without having separate software programs doing different things.
