Creates a boundary surface from three or four input curves. A boundary surface is a fast way to create a surface to fill an area bounded by three or four curves whose ends touch.

The curve ends do not need to touch unless the "endPoint" attribute is true.

Note that if surface curves (such as isoparms or trim edges) are used to form the boundary surface, the resulting surface has no continuity options. Birail surfaces should be used in this case.
