All the examples I have seen of SUBD use have been free form. Everything I do is off of plans. However, I read that SUBD could be created from REVOLVE.
So I used the WIP and did a revolve that I had lying around. It was interesting to see that NURBS and SUBD can work together. However, the revolve has a slightly perverse shape (Not the upper edge of the saucer):
Is this something that SUBD is not appropriate for or is there something else that needs to be done that I have left out.
Also, it seems to me that RHINO ought to remember across sessions if the user wants subd or nurbs. The option on revolve resets to nurbs on exit.
