See discussion of optional lines below.

I think that as long as it accomodates studs where they need to go, which it
appears to, and looks close enough, it's fine.

Interesting. Because of the very noticable difference in POV-Ray when
circle-based primitives are used, I would suggest using the disc and cyli
primitives whenever possible. Perhaps we should update the macaroni brick to
use the primitive's as well.

The optional line between these two surfaces would be:
5 24 17.80 8 49.23 17.80 0 49.23 10 8 50 25.31 8 46.96 -or-
5 24 17.80 8 49.23 17.80 0 49.23 10 0 50 25.31 0 46.96 -or-
5 24 17.80 8 49.23 17.80 0 49.23 10 8 50 25.31 0 46.96 -or-
5 24 17.80 8 49.23 17.80 0 49.23 10 0 50 25.31 8 46.96 -or-
If two surfaces are arranged like this:
a -- c -- e
| | |
b -- d -- f
then the optional line between them would be any of the following:
5 24 c d a e
a f
b e
b f
Hope this is clear enough to help!
