Steve, I agree, while I am not a pro with Alias - I do use another surface modeler (Rhinoceros). The real issue is the visual interface involved with 3D computer modeling. You're interpreting a 3D model on a 2D screen. We'll just have to see where the technology takes us. On the other hand, "Never say never" - I am a mechanical engineer by trade and I remember a fellow engineer telling me computers are only good for drawing circles and straight lines. That was in 1983 - Now look how far we have come!
