IfcCableCarrierSegmentType

Definition from IAI: The IfcCableCarrierSegmentType is a flow segment that is specifically used to carry and support cabling.

HISTORY: New entity in IFC 2x2.

Use Definitions

An IfcCableCarrierSegmentType is used to define the common properties of a cable carrier segment that may be applied to many occurrences of that type. A cable carrier segment is used to carry and supports components of a cabling system. Cable carrier segment types may be exchanged without being already assigned to occurrences.

The occurrences of the IfcCableCarrierSegmentType are represented by instances of IfcFlowSegment or its subtypes.

Property Set Use Definition:

The property sets relating to the IfcCableCarrierSegmentType are defined by the IfcPropertySet and attached by the IfcRelDefinesByType relationship. It is accessible by the inverse IsDefinedBy relationship. The following property set definitions specific to the IfcCableCarrierSegmentType are part of this IFC release:

Pset_CableCarrierSegmentTypeCableLadderSegment: specific property set for the properties of a segment of a cable ladder, if available
Pset_CableCarrierSegmentTypeCableTraySegment: specific property set for the properties of a segment of cable tray, if available
Pset_CableCarrierSegmentTypeCableTrunkingSegment: specific property set for the properties of a segment of cable trunking, if available
Pset_CableCarrierSegmentTypeConduitSegment: : specific property set for the properties of a segment of electrical conduit, if available

Geometry Use Definitions

Representations of the type are defined as representation maps (at the level of the supertype IfcTypeProduct). These are assigned at the occurrence through the IfcShapeRepresentation.Item being an IfcMappedItem.
