class Ifc4::IfcCableFitting : public Ifc4::IfcFlowFitting

A cable fitting is a fitting that is placed at a junction, transition or termination in a cable system.

HISTORY New entity in IFC2x4

Type Use Definition IfcCableFitting defines the occurrence of any cable fitting; common information about cable fitting types is handled by IfcCableFittingType. The IfcCableFittingType (if present) may establish the common type name, usage (predefined type), properties, materials, ports, composition, assignments, and representations. The IfcCableFittingType is attached using the IfcRelDefinesByType objectified relationship and is accessible by the IsTypedBy inverse attribute. If the IfcCableFittingType has ports or aggregated elements, such objects are reflected at the IfcCableFitting occurrence using the IfcRelDefinesByObject relationship.

Property Use Definition The property sets relating to this entity are defined by IfcPropertySet and attached by the IfcRelDefinesByProperties relationship. They are accessible by the IsDefinedBy inverse attribute. Property sets may also be specified at the IfcCableFittingType, defining the common property data for all occurrences of the same type. They are then accessible by the IsTypedBy inverse attribute pointing to IfcCableFittingType.HasPropertySets. If both are given, then the properties directly defined at IfcCableFitting override the properties defined at IfcCableFittingType. Refer to the documentation at the supertype IfcFlowFitting and ancestors for inherited property set definitions. The following property set definitions are applicable to this entity: Pset_CableFittingTypeCommon (PSET_TYPEDRIVENOVERRIDE)

Quantity Use Definition The quantities relating to this entity are defined by IfcElementQuantity and attached by the IfcRelDefinesByProperties relationship. They are accessible by the IsDefinedBy inverse attribute. The following base quantities are defined and shall be exchanged with the IfcElementQuantity.Name = ‘BaseQuantities’. Other quantities, being subjected to local standard of measurement, may be defined with another string value assigned to Name. In this case a valid value for MethodOfMeasurement shall be provided.

Qto_CableFittingBaseQuantities

Material Use Definition The material of the IfcCableFitting is defined by IfcMaterialProfileSetUsage or as a fallback by IfcMaterial, and attached by the RelatingMaterial attribute on the IfcRelAssociatesMaterial relationship. It is accessible by the HasAssociations inverse attribute. Material information can also be given at the IfcCableFittingType, defining the common attribute data for all occurrences of the same type. The following keywords for IfcMaterialProfileSet.MaterialProfiles[n].Name shall be used:

Casing: Material from which the casing is constructed. Conductor: Material from which the conductors are constructed, such as Aluminium or Copper.

Connection Use Definition The IfcCableFitting may be connected to other objects as follows using the indicated relationship:

ENTRY

IfcPipeSegment (IfcRelConnectsElements): For equipotential bonding, may represent a clamp that is attached from a pipe or other conducting element of an earthing system.

EXIT

IfcPipeSegment (IfcRelConnectsElements): For equipotential bonding, may represent a clamp that is attached to a pipe or other conducting element of an earthing system.

Port Use Definition The distribution ports relating to the IfcCableFitting are defined by IfcDistributionPort and attached by the IfcRelConnectsPortToElement relationship. If the cable fitting occurrence is defined by IfcCableFittingType, then the port occurrences must reflect those defined at the IfcCableFittingType using the IfcRelDefinesByObject relationship. Ports are specific to the IfcCableFitting PredefinedType as follows indicated by the IfcDistributionPort Name, PredefinedType, and FlowDirection:

CONNECTOR

Input (NOTDEFINED, SINK): The input of the connector. Output (NOTDEFINED, SOURCE): The output of the connector.

ENTRY

Output (NOTDEFINED, SOURCE): The output of the connector.

EXIT

Input (NOTDEFINED, SOURCE): The input of the connector.

JUNCTION

Head (NOTDEFINED, SOURCE): The input of the connector. Output#1 (NOTDEFINED, SINK): An output of the connector. Output#2 (NOTDEFINED, SINK): An output of the connector.

TRANSITION

Input (NOTDEFINED, SINK): The input of the connector. Output (NOTDEFINED, SOURCE): The output of the connector.
