getting rid of hidden or underlying NURBS surfaces

Michael,

Referring to my previous post on problems with hidden or underlying NURBS surfaces "resurfacing" when .iges models are imported to Prosurf and exported as .dxf 3D meshes.

Are you familiar with different features of the .iges file format. When importing .iges to Prosurf the following dialog box appears. Do you think checking or unchecking some of these choices would help me get rid of the disturbing hidden or underlying NURBS surfaces???



Thanks in advance,

Boatstalker
