I looked at Tor's code that Hugo posted and he uses a completely different
method. His method makes a torus segment with ends on two control points. My
method makes a torus segment which may pass through no control points and
has its ends at the midpoints between a point and its previous and next
points.

I considered Tor's method, but the method I chose is more appropriate for
the kinds of objects I designed it to create. (Cables, tubing, piping, etc.)
Attached is a picture showing the same set of control points and the output
of each macro. My macro produced the red sweep, Tor's the blue.
