Hello John,
I'm not quite sure to understand what you mean (English is not my mother
language as you can read), because Domes are Hoolow, as you can see on
the little sample below.
For the second point, I must admit that those domes are not Geodesic and
the meridians (as on the earth) are closer to each other as you approach
the pole.
I send you the beta version by pm (but a further enhanced version is on
its way (features asked by other beta-tester...))

Excellent!
Sure, I'll beta test.
What I am trying to do is build a 'dome city' - along the lines of a
geodesic dome, but for (redundancy) I'm building a city with 4 'lobes'.
I was trying to make the glass (plastic, etc) of the dome actually have
glass IOR, so that it looks like a series of window panes. When I first
starting doing this is when I noticed the bug I commented on earlier.
What was happening is that the entire 'dome' is one big block of glass,
rather than a hollow shell.
One idea I had, had been to take 2 domes, and CSG the inner out of the
larger one to get a 'hollow' dome, i.e. panes of glass. However, this
would probably make the glass not quite all the same thickness.
You can see the weird way the buildings look in the attached
screenshot, which gives you a rough idea of what I"m going for (most of
the city isn't detailed properly, and a few buildings stick up too high,
but you get the general idea).
(This is to be a dome city on Mars).
The problem with the facet/wire spacing is apparent when you ok at the
top of the 'city' - the lines in the dome get quite closely spaced.
Look at CityBigger-1, everything doesn't look too bad (other than the
bad problem with the IOR, given that the whole thing is one block of
'glass'). However, look at CityBigger-2.jpg, you can see how the lines
at the top of the dome are looking a bit odd.
The dome settings:
EpiCycloide, 4 sides, Parameter 1.0
Slope: Sinus-Cosinus, twist 0.
Window: sans.
(faces, wires, etc). You can see a rough idea of what I'm making in
the PNG shot of the Moray workspace, although I"ll need to make that a
separate post.

Hello,
The problem with degenerated triangles in meshes is fixed (if you
are in a hurry with this one I can send it to you).
Could you give more information about hollow dome (meshes are
hollow)
The other problem of evenly spaced meridians is a bit more tricky
(at least for certain slopes), I hope I'll find some time this week to
have a look on it.
