Coming from Pro/CDRS or Desiger, AutoCAD 2006, Alias Studio, Rhino has been the most easy to learn and use 3D software by far. I don't use it for animation or particles, but for product design and scene creation it does a superb job. Simple compared to those other programs I've worked with in the past for real world designing.
