6.2.3.1 IfcDistributionChamberElement

Elément de chambre de distribution
Schacht / Graben / Revisionsschacht

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.

Table 206 — IfcDistributionChamberElement Material Constituents

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:
