Converting to NURBS

The Convert to NURBS command converts planar objects and 3D polygons into NURBS curves, and converts the faces of solids to NURBS surfaces. This is a quick way of creating NURBS curves from circles and arcs, or NURBS surfaces from an extrusion, sweep, or other solid.

To convert to NURBS curves or surfaces:

Select the object or solid to convert to NURBS surfaces.

Select the command.

The selection is converted to a NURBS surface or a NURBS curve, as reflected in the Object Info palette.

If the solid consisted of several faces, the conversion results in a group of NURBS surfaces. Select Modify > Ungroup to access the individual NURBS surfaces that make up the solid.
