Thanks for the positive feedback :)

Try turning off normalization by hitting the keystrokes '0N' in the
camera window, or by opening the Appearance panel and clicking on the
"None" line of the Normalization control box. If that fixes things,
then turn this on by default by putting the line

 (normalization allgeoms none)

in a file called ".geomview" in your home directory.

Yes, that's also possible. When you load geometry you can
give an explicit name to each object. For instance:

(geometry thing1 { QUAD 
-1 -1 0 
1 -1 0
1 1 0
-1 1 0
})

(geometry thing2 {SPHERE 1 0 0 0})

It doesn't matter whether these geometry commands all come from a
single external module or from different modules. This is a totally
orthogonal issue to the normalization question. (Or it's possible I
didn't fully understand your question.)

Hope this helps,
