For anyone following this thread, I found a way to rotate a tube and not have the mesh skew the way it does for both Remote Displacement and Revolute Joint.nI opened the model in this thread: and found a third way to constrain a tube on its axis while also providing a rotation input. That was to use a Cylindrical Coordinate System. That provides a path for anyone needing to rotate a workpiece and use a tool to simulate turning.nIt does not answer the question posed by the original post, why does a Remote Displacement (or the Revolute Joint as suggested by ) skew the mesh?n
