摘要： A positioning device includes a computer including a stored design file, such as a CAD file, for positioning a selected portion of the design on a workpiece. In a first embodiment, a base unit houses an extensible cable including a free end for placement by a user at a design point on the workpiece. A turn carriage freely rotates about a turn axis to follow cable movement. In output mode, the user is directed to move the cable free end toward the portion of the design and a cable tensioning motor adjusts the tension in the cable sufficiently to indicate when cable free end is at a distance to the portion of the design. Other embodiments include: a turn carriage servoed motor for rotating the turn carriage to follow the cable; and a pitch carriage and servoed motor for rotating the pitch carriage for following the cable.
