IfcBoundaryNodeConditionWarping

Definition from IAI: IfcBoundaryNodeConditionWarping inherits all attributes from IfcBoundaryNodeCondition and includes additionally the possibility to define a value describing the warping stiffness.

If a warping stiffness value is needed, an instance of this entity must be used. Otherwise, an instance of IfcBoundaryNodeCondition is adequate.

NOTE: Instances of the entity IfcBoundaryNodeConditionWarping are used e.g., to define the boundary condition for instances of IfcStructuralPointConnection or IfcRelConnectsStructuralMember pointing to a structural node connection.

HISTORY: New entity in Release IFC2x edition 2.
