I have done it by generating an arch, then clipping it in Y, but it's clumsy
and the keystone has to be generated separately.  There's probably some
better way to do it, but my math is especially weak in knowing how to define
things as required.

The strongest point about POV-Ray isn't the program itself, but the
fantastic amount of help that's available.  Almost anything you want to do
with it, someone has probably already written code and made it available,
usually as a freebie.  As I don't look for photo quality in my renders, just
something better than what I can get with a 3d CAD, I'm always pleased with
the results.  Others have proved that photo quality is possible, I might get
to that point, but I might also die first.

Time spent in browsing the utilities sections, links, will prove to cut the
workload dramatically.  Many thanks to those that have made the code
available.
