IfcCableSegmentType: public Ifc4x3_rc1::IfcFlowSegmentType¶
The flow segment type IfcCableSegmentType defines commonly shared information for occurrences of cable segments. The set of shared information may include:
common properties with shared property sets common representations of shape common materials common composition of elements common ports applicable assignment of process types
It is used to define a cable segment specification (i.e. the specific product information, that is common to all occurrences of that product type). Cable Segment types may be exchanged without being already assigned to occurrences. Occurrences of IfcCableSegmentType are represented by instances of IfcCableSegment.
HISTORY: New entity in IFC2x2
Property Set Use Definition The property sets relating to this entity are defined by IfcPropertySet and attached by the HasPropertySets attribute. Refer to the documentation at the supertype IfcFlowSegmentType and ancestors for inherited property set definitions. The following property set definitions are applicable to this entity: Pset_CableSegmentTypeCommon Pset_ElectricalDeviceCommon
The following property set definitions are applicable to this entity according to the PredefinedType attribute:
Pset_CableSegmentTypeBusbarSegment (BUSBARSEGMENT) Pset_CableSegmentTypeCableSegment (CABLESEGMENT) Pset_CableSegmentTypeConductorSegment (CONDUCTORSEGMENT)
Material Use Definition The material of the IfcCableSegmentType is defined by IfcMaterialProfileSet or as a fallback by IfcMaterial, and attached by the RelatingMaterial attribute on the IfcRelAssociatesMaterial relationship. It is accessible by the HasAssociations inverse attribute. The following keywords for IfcMaterialProfileSet.MaterialProfiles[n].Name shall be used:
‘Conductor’: The material from which the conductor is constructed such as Aluminium or Copper. ‘Insulation’: The material from which the insulation is constructed such as PVC, PEX, EPR, etc. ‘Screen’: The material from which the screen that covers the sheath is constructed (mantel) such as Aluminium, Copper, Steel , Lead. ‘Sheath’: The outer sheathing of the cable which may be color-coded.
Composition Use Definition The IfcCableSegmentType may be aggregated into components using IfcRelAggregates where RelatingObject refers to the enclosing IfcCableSegmentType and RelatedObjects contains one or more components. Components are reflected at occurrences of this type using the IfcRelDefinesByObject relationship. Aggregation use is defined for the following predefined types:
CABLESEGMENT: May contain IfcCableSegment components having PredefinedType CORESEGMENT. Cable segments may be aggregated into cable cores. CORESEGMENT: May contain IfcCableSegment components having PredefinedType CONDUCTORSEGMENT. Cable cores may be aggregated into cable conductors.
Port Use Definition The distribution ports relating to the IfcCableSegmentType type are defined by IfcDistributionPort and attached by the IfcRelConnectsPortToElement relationship. Ports are reflected at occurrences of this type using the IfcRelDefinesByObject relationship. Refer to the documentation at IfcCableSegment for standard port definitions.
Identifies the predefined types of cable segment from which the type required may be set.
