IfcDistributionChamberElement: public Ifc4x2::IfcDistributionFlowElement¶
A distribution chamber element defines a place at which distribution systems and their constituent elements may be inspected or through which they may travel.
An IfcDistributionChamberElement is a formed volume used in a distribution system, such as a sump, trench or manhole. Instances of IfcDistributionSystem or IfcDistributionFlowElement may be related to the IfcDistributionChamberElement enabling their location in or at the chamber to be determined.
HISTORY: New entity in IFC2x2
Type Use Definition IfcDistributionChamberElement defines the occurrence of any distribution chamber element; common information about distribution chamber element types is handled by IfcDistributionChamberElementType. The IfcDistributionChamberElementType (if present) may establish the common type name, usage (predefined type), properties, materials, ports, composition, assignments, and representations. The IfcDistributionChamberElementType is attached using the IfcRelDefinesByType objectified relationship and is accessible by the IsTypedBy inverse attribute. If the IfcDistributionChamberElementType has ports or aggregated elements, such objects are reflected at the IfcDistributionChamberElement occurrence using the IfcRelDefinesByObject relationship.
Property Set 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 IfcDistributionChamberElementType, defining the common property data for all occurrences of the same type. They are then accessible by the IsTypedBy inverse attribute pointing to IfcDistributionChamberElementType.HasPropertySets. If both are given, then the properties directly defined at IfcDistributionChamberElement override the properties defined at IfcDistributionChamberElementType. Refer to the documentation at the supertype IfcDistributionFlowElement and ancestors for inherited property set definitions. The following property set definitions are applicable to this entity: Pset_DistributionChamberElementCommon

Material Use Definition The material of the IfcDistributionChamberElement is defined by IfcMaterialConstituentSet 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 IfcDistributionChamberElementType, defining the common attribute data for all occurrences of the same type. The following keywords for IfcMaterialConstituentSet.MaterialConstituents[n].Name shall be used:
‘Base’: The material from which the base of the duct is constructed. ‘Cover’: The material from which the access cover to the chamber is constructed. ‘Fill’: The material that is used to fill the duct (where used). ‘Wall’: The material from which the wall of the duct is constructed.
Whether the optional attribute PredefinedType is defined for this IfcDistributionChamberElement.
