Creates surface defined by four splines. The order of picking the splines matters - they should form a closed loop. If you get a weird looking mesh, try once again starting with another of the four splines:

Note that if any of the splines are animated, the resulting mesh is animated, too.

Example usage would be spiral ductwork, screw threads, flexible metal tubes, circular ramps etc. No smoothing groups are assigned, for smooth look either use Smooth modifier or add points to the spline profile.

Since I've written a few functions to make my life easier while working on the Gear primitive (plus one that I later discarded, intended to fill holes), I figured I could just as well make a quad cylinder as a much simpler example how to tie these functions together. Enjoy and feel free to rip the code apart and reuse it.
