Rebuilds the shape of NURBS surfaces and curves.
Summary
If you have difficulties editing the control vertices or there are too many control vertices, you can rebuild a surface or curve with less control vertices in the U or V direction. CVREBUILD also allows you to change the degree of the surface or curve.
If you select a surface, the Rebuild Surface dialog box is displayed. If you select a spline, the Rebuild Curve dialog box is displayed.
