class Ifc2x3::IfcStructuralCurveConnection : public Ifc2x3::IfcStructuralConnection

Definition from IAI: Instances of IfcStructuralCurveConnection describe edge ‘nodes’, i.e. edges where two or more surface members are joined, or edge supports. Edge curves may be straight or curved.

HISTORY: New entity in IFC 2x2.

IFC 2x4 change: Attribute Axis added, allowing for skewed supports. Use definitions added.

Coordinate Systems:

See definitions at IfcStructuralItem. The local coordinate system is established by the reference curve given by topology representation and by the attribute Axis. The local x axis is parallel with the tangent on the reference curve. The local z axis is located in the surface which is created by sweeping Axis along the reference curve and is directed according to Axis. The local y axis is directed such that x,y,z form a right-handed Cartesian coordinate system.

Topology Use Definitions:

Instances of IfcStructuralCurveConnection shall have a topology representation which consists of one instance of IfcEdge or a subtype, representing the reference curve of the curve connection. See definitions at IfcStructuralItem for further specifications.

Informal propositions:

The reference curve must not be parallel with Axis at any point within the curve connections’s domain.
