NURBS to Bézier workflow
Select tool.
Select one or more multi-span surfaces. These can be regular or trimmed surfaces.
Click the Split button in the lower right corner of the view window.
The selected surfaces are split into several single-span (Bézier) surfaces. The resulting surfaces are not grouped.
The total number of Bézier surfaces created is posted in the promptline. The Bézier surfaces have the same U and V degrees as the original surface.
Degree 5 NURBS surface of 4 x 2 spans split into eight Bézier surfaces.
Repeat steps 2 and 3 to continue splitting surfaces if desired.
