is specified by the SURFTAB1 system variable. It is the same for each curve;
therefore, the distance between the vertices along the two curves differs if the
curves are of different lengths.
The N direction of the mesh is along the boundary curves. If both boundaries
are closed, or if one is closed and the other is a point, the resulting polygon
mesh is closed in the N direction and N equals SURFTAB1. If both boundaries
are open, N equals SU 1, because division of a curve into n parts
requires n + 1 tabulations.
Selecting objects at the same ends creates a polygon mesh.
Selecting objects at opposite ends creates a self-intersecting polygon mesh.
