Try as I might, I can't work out how to get this bevel to work.
The arch is a box with a cylinder. The cylinder is then y-scaled to the
desired shape.
The bevel is done with a cone in the same y-scale, however this means
the the center approaches a 0-degree bevel rather than the 45-degrees at
both sides.
It is possible to fix this?
Cheers!
Rick

I don't know how to fix the CSG, but I think you could do the same thing
with a spline & prisms. Create a spline in the shape of your arch. Use the
spline to make 2 prisms, one with a linear sweep for the arch and another
scaled slightly larger with a conic sweep for the bevel.

Have a look at Supercone() in the manual section 3.6.12.1 shapes.inc
