IfcRelConnectsPathElements

Definition from IAI: The IfcRelConnectsPathElements relationship provides the connectivity information between two elements, which have a path information. Currently it is applied to IfcWall and IfcWallStandardCase.

The objectified relationship provides all additional information required to describe the connection between two path based elements that might have single or multiple layers of material. The connection type specifies where at the path based element a connection is given (at the start, in the middle or at the end).

> HISTORY: New entity in IFC Release 1.5.

Illustration:

The following figure shows the application of IfcRelConnectsPathElements with the ConnectionGeometry of type IfcConnectionCurveGeometry.

| The example shows the connection relationship between two instances of IfcWallStandardCase using the IfcRelConnectsPathElements relationship. The ConnectionGeometry defines the CurveOnRelatingElement and CurveOnRelatedElement, both are of type IfcPolyline.
