You might need a vacuum fixture(+/- .0002 flatness) without vacuum bleeding groove which may cause conductivity changed or cutter will leave marks. Vacuum pressure should be at 20 to 25 pounds/ square inch. Locate part on suface fixture, use industrial white tape to seal the vacuum around part...
I'd rather use the Catia V5 and ProE or at least Mastercam V9.0. They are really awsome about Models convertered. They are linked and communicated each others. Try it you will see.
I tried to go to the optional but somehow I couldn't save the model like iges. have I done something wrong with these step. Please show me, really appreciated
