IfcGeometricSet: public Ifc4::IfcGeometricRepresentationItem¶
Definition from ISO/CD 10303-42:1992: This entity is intended for the transfer of models when a topological structure is not available.
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 ISO 10303-42 entity: geometric_set. 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. 190 for the final definition of the formal standard.
HISTORY: New entity in IFC Release 2x.
Subclassed by Ifc4::IfcGeometricCurveSet
The geometric elements which make up the geometric set, these may be points, curves or surfaces; but are required to be of the same coordinate space dimensionality.
