Using Reference Geometry
You can use a selected reference geometry to apply restraints. The reference can be a plane, axis, edge, or face. Using this option you can prescribe restraints on vertices, edges, faces and beam joints.
In an assembly, you can use reference geometry from the assembly or the components (parts and sub-assemblies) of the assembly.
The number of degrees of freedom that can be restrained depends on the mesh type and the selected reference.
