Abstract: The present invention relates to a computer aided design and manufacturing system. The system comprises a platform suspended by means of three pairs of supportive legs which are coupled at triangularly spaced-apart locations by means of three universal joints, each of which couples to one end of each of the two legs of a respective pair. The two legs of each pair extend from their respective universal joint in divergent directions to spaced-apart locations in an overhead mounting where each leg is drivingly engaged by a respective gimbal-mounted electric motor arranged to move the leg in its own longitudinal direction. The platform position and orientation can be controlled by appropriate operation of the six leg drive motors.
