I've written a small program (C sauce included) that will take a PLY
file, fresh from DXF2RSD, and get rid of all duplicate vertices, normals
and polygons.

Why? Well, memory for one thing, but the other main thing is that if you
want to create a polygon and then manually much around with their
vertices, you'll have to adjust all their normals too! After crunching,
you only have to adjust one for similar planes.
