Hi Jon,

re:

That's definitely worth a try. It's not automatically assured that it will help, it depends on what they put in the .igs file. Like for a sphere object do they write it as a sphere object in the IGES file or do they write out 1000 little flat facets for the sphere.

But if they remember that the object was a sphere and can write out that higher level representation then that could work.
