Right. It was easier for my brain to set up a spreadsheet and try each
combination of beam-length and stud-pitch than to work out which beams
are the right length to make up the hypotenuse(sp?) of a pythagorean
triangle.
Note: actually, you can use any length beams as the diagonal brace
between other beams. You just don't a spacing on the other beams that
fits with lego-standard.

Neat pics.

No matter what, I think constructions like these take too many pieces.

Well, since the design is nowhere near complete, I can make any plan I
want. But the transparent pieces aren't going to be the problem. I've
been slowly accumulating those for some time. I've got a lot of 12H
dome pieces, and most of the pieces I need to build the greenhouse, as
it depicted on the web pages. The real problem is that I have nowhere
near enough Technic pieces to build the frame. And then I need a ton of
large plates to put in floors.
I don't seem to design lightweight. All of the model studies I've done
use a lot of pieces.
