Abstract: A drawing template set includes a planar anchor ring having an outer diameter and an inner diameter, a rotary increment scale marked at least part way along the outer diameter, and a first registration interface at at least one point on the inner diameter, and a planar template having an outer diameter providing a slip fit into the inner diameter of the planar anchor ring, one or more through slots or other openings enabling a user to draw specific lines and shapes on a drawing surface to which the template may be applied, and a second registration interface on the outer diameter matching the first registration interface of the planar anchor ring, enabling the user place the planar template in the anchor ring for use, to remove it as desired, and to replace it with a different template fashioned for a different purpose.
