Rotation directional restraints with gaps are considered specialty items. Usually, they used only in sophisticated expansion joint or hinge models.
Bi-Directional Rotational Restraint With Gap
Allowable rotation of 5º in either direction about the Z-axis before resistance to rotation is encountered.
Hinge Assembly With Directional Rotational Restraint
The hinge assembly at node 50 can rotate relative to assembly at node 55 only in the positive direction about the Z-axis.
