IGES Geometry Import Converter

This geometry import converter reads in IGES 4.0 and later ASCII files. The entire IGES specification is parsed and stored temporarily in memory but only entities 106 (polygons) and 128 (NURB patches) are currently sent to the internal geometry database.

All polygonal data will be stored internally using one 'Indexed Polygon' (mesh) primitive. NURB data will be stored internally in their native form.
