Hi, For demo purposes I'm looking for a rail arm solidworks part. What I need is to present a car plant with a rail that can take one part (e.g. a door) from one station and move it to another station. The rail itself is a simple profile that is extruded (or swept) along a path. I need the arm that slides along the rail with a tray or a sort of a gripper that can hold the door. It is just for a demo purpose, so I any kind of such an arm will do. I looked in the model library sw site but couldn't find any sample. Thanks, Steph.
