#### 5.4.3.9 IfcRelConnectsPorts

| Connection de ports
| Verbindet Anschlüsse - Relation

An IfcRelConnectsPorts relationship defines the relationship that is made between two ports at their point of connection. It may include the connection geometry between two ports.

The objectified relationship IfcRelConnectsPorts is required for defining how two instances of IfcPort connect together. Each of the ports is logically contained within the IfcDistributionElement by using the ordered collection IfcRelNests.

> HISTORY New entity in IFC2.0, modified in IFC2x.

> IFC4 CHANGE Previously the containment of the IfcPort within the IfcDistributionElement had been realized using the IfcRelConnectsPortToElement relationship.
