Roller constraint
When you define a roller constraint, you choose:
A planar face to constrain
A direction for the roller axis. The translational degree of freedom (DOF) and rotational DOF for this axis are free. All other DOFs are fixed.
Note:
When you define a roller constraint on geometry, a local coordinate system is created and applied to the underlying nodes. If local coordinate systems already exist at these nodes, the constraint's coordinate system may overwrite them. For example, if you define a constraint on a location where spring elements are defined, the constraint's coordinate system may overwrite the spring element definitions.
