This code allows one to convert a NURBS Surface to an IGES surface file for import into a CAD program. Entity 128 is used and is the only entity type output. NURBS curves could be output with some modification. This code is rough but works for what I am doing.

Attached IGES format guidelines to help understand it. All the lines (in the *.igs file) on the right MUST line up or the file will not open up.
