#### 6.2.3.14 IfcFlowSegment

| Tronçon d'installation fluides
| Verteiler (allgemein)

The distribution flow element IfcFlowSegment defines the occurrence of a segment of a flow distribution system.

The IfcFlowSegment defines a particular occurrence of a segment inserted in the spatial context of a project. The parameters defining the type of the segment and/or its shape are defined by the IfcFlowSegmentType, which is related by the inverse relationship IsDefinedBy pointing to IfcRelDefinesByType.

> HISTORY New entity in IFC2.0.

> IFC4 CHANGE This entity has been deprecated for instantiation and will become ABSTRACT in a future release; new subtypes should now be used instead.
