#### 6.1.3.1 IfcDistributionFlowElement

| Elément de distribution de fluide
| Komponente der TGA (allgemein)

The distribution element IfcDistributionFlowElement defines occurrence elements of a distribution system that facilitate the distribution of energy or matter, such as air, water or power.

> EXAMPLE Examples of distribution flow elements are ducts, pipes, wires, fittings, and equipment.

> HISTORY New entity in IFC2.0.

> IFC4 CHANGE Ports are now primarily defined using IfcRelNests to enable definition of ports at type definitions (both forward and backward compatible), provide a logical order, and reduce the number of relationship objects needed. The relationship IfcRelConnectsPortToElement is still supported, however is now specific to dynamically connected ports.
