I have a customer who uses Inventor 2010. He can't seem to change export tolerance from 0.01mm (STP, IGS, SAT). Is there a simple way to fix this? Thanks for any help!

edit: I'm talking of the tolerance value that shows up when the file is imported. In this case the surface needs to be micro-faceted but Inventor does an unwanted arc-fitting operation. My minimum requirement would be to get arc fitting at 0.0005 tolerance if facets are not possible. The same applies to dxf.
