7.10.3.20 IfcStructuralPointConnection

7.10.3.20.1 Semantic definition

Instances of IfcStructuralPointConnection describe structural nodes or point supports.

*Coordinate Systems*:

See definitions at IfcStructuralItem. The local coordinate system is established by the reference point given by topology representation and by the attribute ConditionCoordinateSystem.

Defines a coordinate system used for the description of the support condition properties in SELF\IfcStructuralConnection.SupportCondition, specified relative to the global coordinate system (global to the structural analysis model) established by SELF.\IfcProduct.ObjectPlacement. If left unspecified, the placement IfcAxis2Placement3D((x,y,z), ?, ?) is implied with x,y,z being the coordinates of the reference point of this IfcStructuralPointConnection and the default axes directions being in parallel with the global axes.

Reference Topology General

Instances of IfcStructuralPointConnection shall have a topology representation which consists of one IfcVertexPoint, representing the reference point of the point connection. See definitions at IfcStructuralItem for further specifications.

This concept can be applied to the following resources:
