ABSTRACT:
A geometrical layout tool and method for locating a plurality of target points spaced apart over a particular area from a single reference point located within that area which is defined by the intersection of mutually perpendicular lines. A template placed over these lines has a central opening at the intersection and indicia at its periphery which register respectively with the lines. A center anchoring pin holds the template against movement, and a target line indicator is rotatably adjustable about the pin for alignment with a selected target point. A chalk line and tape measure or a laser may be mounted on the pin to make direction and distance determinations of the selected target point from the reference point.
