does so much when you've got 300,000 polygons (as was the case with my
Kodiak when I tried this).

I'm assuming you are generating a single, flattened stream of input,
instead of defining subobjects which correspond to the subfiles in a
model.  If I'm wrong about that, ignore the rest of this message.

One thing to do is to intercept any references to stud*.dat files, and
replace them with the equivalent cylindrical shape.  These files
typically have hundreds of references in even medium-sized models.

See <http://www.ldraw.org/memorial/archive/FAQ/Primitives_Reference> for
the definitions of most primitives.  There are a number of simple
geometric primitives that could be replaced a single object.

<Cough!> Okay, time to crank my brain I guess. I'm going to be working with a .dxf file. If anyone has more advice specific to those, then I'd really appreciate it. Steve, thanks for the help. I'm going to give this a go, but when ever it comes down (...) (25 years ago, 16-Mar-00, to lugnet.cad)
