Well, spurred on by Todd's request, I finally did what I've wanted to do
for a while ... write a replacement for MC's bogus "Combine Into
Surface" command ... it will take any combination of selected arcs,
lines, polygons, and polylines and combine them into a surface.

It doesn't care if the ends are exactly touching ... or even if they are
near each other. It just finds the nearest end and connects to that.

Why is it so hard for MC to get this one right?

Comments, suggestions and bug reports requested ...
