class Ifc4x2::IfcFaceBasedSurfaceModel : public Ifc4x2::IfcGeometricRepresentationItem

Definition from ISO/CD 10303-42:1992: A face based surface model is described by a set of connected face sets of dimensionality 2. The connected face sets shall not intersect except at edges and vertices, except that a face in one connected face set may overlap a face in another connected face set, provided the face boundaries are identical. There shall be at least one connected face set.

A connected face set may exist independently of a surface model.

NOTE Corresponding STEP entity: face_based_surface_model. Please refer to ISO/IS 10303-42:1994, p. 188 for the final definition of the formal standard.

HISTORY: New entity in IFC Release 2x.

Informal propositions:

The connected face sets shall not overlap or intersect except at common faces, edges or vertices. The fbsm faces have dimensionality 2.
