Part Geometry constitutes the end product of the manufacturing operation. This is also the design model. Design models in various data formats can be imported into VisualCAD. These design models can either be solid models or surface models or even faceted triangle models. VisualCAD allows the import of solid and surface models in the form of industry standard IGES, STEP, Rhino (*.3dm), Stereo-Lithography (both ASCII and binary), Parasolids (*.x_t, *.x_b), and SAT format files. VisualCAD can also directly import AutoCAD (*.dxf and *.dwg) format files.
