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.
