Sweep one or more curves along rails to create a 3D surface. This tool is a variation of the Sweep tool that uses
two rails rather than one extrusion path.
Fill a closed area, defined by boundary curves or surface edges, to create a 3D surface. The new surface maintains
tangent continuity with adjacent surfaces.
Directly edit the geometry of a NURBS surface by performing various operations such as moving, adding, and removing
points; changing the order in the U or V direction; adding weight; and removing trimming curves.
