This recently posted clip sells some of my points quite well: It’s Author likely has decent Nurbs and some SubD background and he checks out some new (and pretty advanced) SubD tools in Alias with the camera running. It’s actually great, that this clip has quite a few issues:
Features aren’t discoverable, operations do fail. The modeling progress, compared to Maya, Blender or similar seems terribly slow. Distinct differences between modeling principles appear oddly blurred. The result of the modeling session is all bumpy. Now imagine reactions: What do those say, who’ve just begun with Nurbs Modelling? What does the Surfacing master say?
