NURBS to Bézier workflow

  1. Select tool.

  2. Select one or more multi-span surfaces. These can be regular or trimmed 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 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.

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