Body Geometry

The Body Geometry concept applies to this entity as shown in Table 74.

RepresentationType | Geometry | Description
--- | --- | ---
Brep | IfcFacetedBrep | All fixtures (all non distribution flow elements, i.e. everything which is not a duct, a pipe, a cable, or a cable carrier) should be defined by an b-rep geometry. This includes also the complex flow fitting elements (e.g. Y branch or T branch) or distribution flow elements with size changes (e.g. reducer).
SurfaceModel | IfcFaceBasedSurfaceModel | If the geometric model consistency of a b-rep shape representation can not be guaranteed (arcwise connected volume bounded by faces, each being connected, oriented, finite, closed 2-manifold), a surface representation based on open shells should be used.
SweptSolid | IfcExtrudedAreaSolid | All "simple" distribution flow elements (general ducts and pipes) are defined by sweep geometry.
SectionedSpine | IfcSectionedSpine | If only the analytical shape is required for which the exact interpolation between the cross sections is not required, a sectioned spine can be used.
CSG | IfcCsgSolid |
Tessellation | IfcTriangulatedFaceSet |
MappedRepresentation | IfcMappedItem | All occurrences of IfcDistributionElement (and its subtypes) should (whenever possible) share a representation map established by the assigned type. The geometric representation of the occurrence is then an IfcMappedItem.

Formal Propositions:

CorrectPredefinedType | : | Either the PredefinedType attribute is unset (e.g. because an IfcCableFittingType is associated), or the inherited attribute ObjectType shall be provided, if the PredefinedType is set to USERDEFINED.
CorrectTypeAssigned | : | Either there is no cable fitting type object associated, i.e. the IsTypedBy inverse relationship is not provided, or the associated type object has to be of type IfcCableFittingType.
