IfcStructuralCurveConnection

Definition from buildingSMART International: Instances of the entity IfcStructuralCurveConnection shall be used to describe 'linear nodes' or 'linear supports', i.e. lines where two or more face members (walls, plates) are joined. All values defined by AppliedCondition are given within a coordinate system which is derived from the local coordinate system defined by this instance.

NOTE: This does not work for each combination of local coordinate system and curve direction. Therefore such combinations shall be forbidden. Normally, whenever possible, the defined local coordinate system should fulfil the constraints outlined above to avoid such a transformation.

HISTORY: New entity in Release IFC2x Edition 2.
