IfcGeometricSet

Definition from ISO/CD 10303-42:1992: This entity is intended for the transfer of models when a topological structure is not available.

Definition from IAI: The IfcGeometricSet is used for the exchange of shape representations consisting of (2D or 3D) points, curves, and/or surfaces, which do not have a topological structure (such as connected face sets or shells) and are not solid models (such as swept solids, CSG or Brep)

NOTE Corresponding STEP entity: geometric_set. Please refer to ISO/IS 10303-42:1994, p. 190 for the final definition of the formal standard.
