Re: Convert STL File to IGES file

Greg S. brings up a good point about using Rhino for the conversion.
There is also a limit of 20,000 facets for such a conversion. For a
complex organic shape it usually just won't work. However if the shape
is reasonable simple Rhino can be a great tool. Once you use the
"meshtonurb" command in Rhino you'll have a file that you can edit. You
can then use the vertices of the facets to place curves on the model to
create a nice smooth surface. It is a bit tedious, but if all you have
is a rough STL file and need it smooth it works quite well. I did a
model earlier this year that was so bad I needed to ask for dimensions
because the designer used the defaults in ProE and it was beyond ugly.

As Greg S. said... What is the goal? Does it need to be surfaced,
modified, etc....
