Abstract: The present invention relates to a drawing apparatus specifically one that allows the user to generate smooth arced and curved lines. The present invention has the advantage to allow the user to create unique arcs and curved lines, rather than follow predetermined templates. The present invention also increases the quality of work because the present invention allows for a unique curve to be created, while French curve templates often require several predetermined templates and curves to be used in combination to create a desired curve. The present invention allows for a unique curve to be saved by tightening the guide track into a locked position. Furthermore the present invention allows for a unique curve to be metered and replicated again at a later time.

Abstract: A three dimensional impression pin screen has two parallel axially aligned perforated spaced plates. Apertures of each plate have a plurality of pins passing through them which have a head on one end and a cap on the other. The heads and caps prevent the pins from passing out of the plates given any orientation of the pin screen. Magnetic strips or pressure strips equal in width to the spacing between the plates contact the shanks of rows or a row of pins between the plates. Strips magnetized on both sides are used to contact the shanks of pins of two adjacent rows. Each magnetic strip is longer than the pin filled apertures of adjacent rows. Each pressure strip contacts a single row of pins. The strips are of a thickness less than the spacing between the shanks of pins in adjacent rows which have the same aperture spacing. Pins are held in displaced positions by attraction to the magnetic strips or by resistance against the pressure strips.
