I've got a sphere sweep with a cubic spline that plots out the outline of half a
propeller blade, and now I want to find a way to "fill in" the space from the
two ends to the loop-back point.

I figured I could start from the midpoint of the two ends, and fan out along the
spline with cylinders, but I'm not sure how to handle the spline, determine its
"length", or return the interpolated values.

Can I plug a spline into a sphere sweep, since it looks like the data structures
are different?
Can I do something with an array to straighten this out?
Trace function?

Trying to search and read documentation and forum text didn't really seem to
give me the sort of thing I'm looking for.

Maybe I ought to go with a mesh object, but I've never used them before, and I'd
rather stick with the few things I know if at all possible.

Thanks!
