stl file comparison

gudday again,

Thanks for the responses on the mesh to stl question. I bit the bullet and
wrote a little piece of code to translate I-DEAS .unv files into .stl files.
It requires a bit of hand fiddling, including fixing the normals afterwards,
but it seems to work. --available if anyone wants it.

I have another problem though.

Is there software available that will compare two stl files of the same
(nominally) part. What I am looking for is some kind of report on the
geometric difference between the two stl files. For instance, I might want
to compare an stl file from a scan of the SLA model with the .stl file it
was made from. Is anyone doing this?

Regards,
Greg.
