Purpose A swept surface is created by sweeping a single generation curve along a path curve using the Extrude, Swept, Birail or Anim sweep Swept Surfaces tools. How to Use To use a Swept surface tool, select it from the Swept surfaces cascading menu, or click one of these icons. Generation and path curves do not have to intersect to construct a surface for Swept , Extrude , or Anim sweep .
Closed curves are valid objects for the generation curve and path curves, but produce open surfaces.
