RelConnectsRigidMember

Rigid Member

A rigid connection between two entities. Rigid Member allows to create connections between nodes (StructuralPoinConnection), 1D members (StructuralCurveMember) and edges of 2D members (StructuralSurfaceMember). Connection could be infinitely rigid or with user defined properties. Maximum of two entities could be connected with one RelConnectsRigidMember.

Notes

Local coordination system is given by first node and its related object.

Non linear behavior of material is handled with "Resistance". The example is shown below.
