IfcDuctSegmentType: public Ifc4x3_rc1::IfcFlowSegmentType¶
The flow segment type IfcDuctSegmentType defines commonly shared information for occurrences of duct 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 duct segment specification (i.e. the specific product information, that is common to all occurrences of that product type). Duct Segment types may be exchanged without being already assigned to occurrences. Occurrences of IfcDuctSegmentType are represented by instances of IfcDuctSegment.
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_DuctSegmentTypeCommon
Material Use Definition The material of the IfcDuctSegmentType 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:
‘Body’: Material from which the duct segment is constructed. ‘Coating’: The outer coating, if applicable. ‘Insulation’: The insulating wrapping, if applicable. ‘Lining’: The inner lining, if applicable.
Port Use Definition The distribution ports relating to the IfcDuctSegmentType 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 IfcDuctSegment for standard port definitions.
