Ooo! Interest. :-D
I have just dropped the site developer an email to see if I can gee him 
up. And if he replies and can set it up. A CSG sub-round sounds a good idea.

Figured out the math for the circular sections.  No rounded edges yet.

Making progress.  The cusp was a nasty one to round off.  The rest should be
easy by comparison.

And round it, you did. Bubbly.

There are still problems when certain arguments to the macro are used, so I'm
holding off on releasing the source until I figure out what's going on.  With
Shay's shape it looks fine, but when I try to reproduce Sam's example, it goes
crazy.  I think the problem has to do with one of the forms of the spherical law
of cosines having 4 solutions (two possible inverse sines of 2 solutions of a
quadratic equation).

You might be over-complicating it in your mind, but it's looking good, Ricky! My
macro goes crazy if certain variables are pushed too far. Notice how I haven't
posted it ;)
