Abstract
Apparatus by which common points in any two conventional adjacent perpendicular orthographic views of an object are utilized to produce isometric, diametric or trimetric views of the object. One form of the apparatus comprises a main plotting member shaped at least in part in the form of an isosceles triangle, and an auxiliary plotting member shaped at least in part in the form of a parallelogram, and means for orienting the auxiliary plotting member at a predetermined angle with respect to the main plotting member. The plotting members are preferably made from rigid, dimensionally stable, transparent plastic material, and lines may be scribed on the plotting members to facilitate positioning of the plotting members for location of common points in the two orthographic views and for orienting the main plotting member with respect to the tertiary axis of the two orthographic views.
