Jan,

I faxed over a page from the Jacob's book "Stereolithography & Other RPM
Technologies." It has the CMM points for the USRPART.STL from the
original study. Unfortunately I have not seen the file (in my catalog,
anyway) in a couple of years. The Clemson site has the file listed, but
it is no good. The file is very old, so I doubt the the CAD information
is known.

Good luck and keep me informed.
