(3D only) Used to construct a B-spline surface that has up to 6 elements (lines, line strings, shapes, arcs, curves, B-spline curves, complex chains, and complex shapes) as edges. Where the number of edges is three to six inclusive, they must meet at their endpoints.

• If there are two edges, a ruled surface, connecting either the closest or the farthest ends, is constructed between the boundaries. If the incorrect surface displays, you can Reset to reverse it.
• If there are four edges, a bi-cubically blended Coons patch is created.
• If there are five or six edges, then three five or six surfaces, respectively, are joined to form one patch.
