Degree of Curves: Is there any good tutorials?

A good understanding of the relationship between a multipoint (piecewise) degree 3 B-spline to the more basic 4 point degree 3 spline can be had by ConvertToBeziers command. See how the new CPs relate to the originals control cage.

Hi Toshiaki,

you can find many good foundational explanations with nicely explanatory images here and here.

Although this is from Autodesk Alias Automotive, many concepts apply to Rhino as well, being a NURBS based surface modelling software. We use both Alias and Rhino, with a good dose of SolidWorks in the menu ; )

Thanks for the link! Great stuff.
Is SolidWorks was a little cheaper I’d like to give it a try…
