IfcSolidModel

Definition from ISO/CD 10303-42:1992: A solid model (IfcSolidModel) is a complete representation of the nominal shape of a product such that all points in the interior are connected. Any point can be classified as being inside, outside, or on the boundary of a solid. There are several different types of solid model representations.

NOTE Corresponding STEP entity: solid_model, only three subtypes have been incorporated into the current IFC Release - subset of manifold_solid_brep (IfcManifoldSolidBrep, constraint to faceted B-rep), swept_area_solid (IfcSweptAreaSolid), and subset of csg_solid (IfcCsgSolid). The derived attribute Dim has been added at this level and was therefore demoted from the geometric_representation_item. Please refer to ISO/IS 10303-42:1994, p. 170 for the final definition of the formal standard.
