Abrégé

A hand layout tool, apparatus, and method directed toward skilled and industrial trades, or for use within other similar mechanical layout and user applications, is presented. The current invention allows the trades technician or user to quickly and accurately determine or otherwise identify the outer or inner centerline of a radial or cylindrical surface feature at a selected or desired angle. Alternately, the current invention can allow the user to quickly, easily, and accurately measure or otherwise determine the included angle between two imaginary planes: a first plane defined as being coincident with the central axis of the cylindrical or radial surface and a first point on an outer or inner cylindrical or radial surface and a second plane defined as being coincident with the central axis of the cylindrical or radial surface and a second point on an outer or inner cylindrical or radial surface.
