New NURBS to Bezier tool

This new surface editing tool splits multi-span NURBS surfaces into single span Bézier patches. It is found in the Palette under Surface Edit > NURBS to Bezier.

The tool operates on both regular and trimmed surfaces. You can also set an option to affect all surfaces or only selected surfaces.

Split multi-span surfaces

1. Choose Surface Edit > NURBS to Bezier .
2. Select one or more multi-span surfaces.
3. 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 prompt line. 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.

4. Repeat steps 2 and 3 to continue splitting surfaces if desired.
