Abstract:
A one-piece Measuring and Drafting Tool comprised essentially of:a. four calibrated ruler segments, such that said four ruler segments are each extending along a common plane and each of the four calibrated ruler segments extends and measures from a common center hole that perforates said Measuring and Drafting Tool at the intersection of said four calibrated ruler segments, and such that each of the four calibrated ruler segments are perpendicular in said plane, to their adjacent ruler segments, and that calibrations on each of the four calibrated ruler segments originate from said common center hole; b. a plurality of guide holes located on one of said four calibrated ruler segments; c. a plurality of alignment tabs located on the top surface of two non-adjacent ruler segments, such that neither of said two non-adjacent ruler segments have guide holes located thereon, and such that an edge of each of the plurality of alignment tabs are in line with the common center hole.
