Spatial Containment

The Spatial Containment concept applies to this entity as shown in Table 59.

Structure | Description
--- | ---
IfcSite | Underground or overground cable carriers are contained within the site.
IfcBuildingStorey | Cable carriers that span multiple spaces are contained within a building storey. If the cable carrier segment spans multiple storeys, it is placed within the storey containing the placement origin, corresponding with the axis origin.

Body Geometry

The Body Geometry concept applies to this entity as shown in Table 60.

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.

PredefinedType | : | Identifies the predefined types of cable carrier fitting from which the type required may be set.

Formal Propositions:

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