Detailed Description

See also:

Class NURBSSurface.

Description:

This class is available in release 2.5 and later only.

This class provides access to the Multisided Blend surface. A Multisided Blend surface is a surface that "fills in" the edges defined by three or four other curve or surfaces. Unliked a regular, two-sided Blend surface, the curves or surfaces edges must form a closed loop--that is, they must completely surround the opening the Multisided Blend will cover.

Note: For the blend to work, the curves that define the blend must form a loop (that is, sequence head to tail, and the ends must match).
