A mechanical programming system for a door has at least one track and at least two links. The track is formed in an arm coupling the door to a door opening in a body. The links are pivotably connected in series between an arm-body interface and an arm-door interface, and transmit rotational motion of the arm about an arm-body hinge axis to the door for rotation about an arm-door hinge axis. At least one link is coupled to the track via a track engaging element. The track has a directional path shape that causes an orientation of at least one link to change as the track engaging element slides along the track in a manner maintaining the door parallel to the door opening during an opening sequence of translating the door from a closed position to an open position while allowing non-parallel orientations of the door during the opening sequence.
