8.19.3.1.1 Semantic definitions at the entity

The abstract entity IfcBoundaryCondition is the supertype of all boundary conditions that can be applied to structural connection definitions, either directly for the connection (e.g. the joint) or for the relation between a structural member and the connection.

NOTE  The boundary conditions are used within other parts, mainly by instances of IfcStructuralConnection (for the definition of supports) and instances of IfcRelConnectsStructuralMember (for the definition of connections between structural members and structural connections).
