This script imports Pro Engineer files to Blender.
This format can be exported from Pro/Engineer and most other CAD
applications. Written at the request of a Blender user. It is almost
identical to RAW format.
Usage:<br>
Execute this script from the "File->Import" menu and choose an SLP file to
open.
Notes:<br>
Generates the standard verts and faces lists, but without duplicate
verts. Only *exact* duplicates are removed, there is no way to specify a
tolerance.
