I originally thought that the numbers were based on the Lego numbers, but my
(admittedly brief) research told me that they didn't, as I found no matches
out of about 6 pieces. I realize that parts will often change numbers (how
many System 2x4 variants are there?) But I intentionally picked pieces that
I couldn't imagine being recast (as checking the part number on a 2x4 seemed
pointless because I didn't expect it to match at all).
Now that I've examined a couple more pieces, I see that you are correct.
I'll make sure I do that for the Duplo parts.

Cool- I'll repost after I fix the naming. I also have some other minor
things to tweak on the 2x4.
And thanks for the other info. I'll hop onto the line substitution and
fast-draw fixes.
One more question: I heavily use the box3#8p.dat primitive. But I have to
add a whole bunch of edges (6) to every single one that I use. Would it
make sense to create a new box3 primitive that has all the associated edges?
This would make it similar to the box4.dat primitive, which includes every
edge that borders on its faces. It would probably cut about 40% from the
file size of every Duplo part, not to mention cut about 80% of the time
required to generate basic parts. If there were such a primitive, what
would be the appropriate name? Alternatively, should I be using the box4 or
box5 primitives and just not worrying about the hidden surfaces?
