4.8.1.4.7 Body SurfaceOrSolidModel Geometry

The Body SurfaceOrSolidModel Geometry is the representation of the 3D shape of a product by surface or solid models and allows for a mixed representation.

The following attribute values for the IfcShapeRepresentation holding this geometric representation shall be used:

The following diagram shows the generic classes and relationships used when applying this concept. In addition, concepts may have particular importance to common or standardised industry practices and scenarios. For these specific usage scenarios, the tables below shows a recommended list of general usage patterns that users may adopt.
