IfcShapeModel represents the concept of a particular geometric and/or topological representation of a product's shape or a product component's shape within a representation context. This representation context has to be a geometric representation context (with the exception of topology representations without associated geometry). The two subtypes are IfcShapeRepresentation to cover geometric models that represent a shape, and IfcTopologyRepresentation to cover the conectivity of a product or product component. The topology may or may not have geometry associated.
