Claims

[Scope of utility model registration request]

(1) A large number of central axes are printed on the surface of a plastic plate at appropriate intervals, and a predetermined perfect circle, ellipse, or equilateral triangle, etc., is printed on the surface of the plastic plate for drafting, with the intersection of the central axes as the center position. In the drafting template formed by drilling holes, dividing lines for error confirmation are printed at two or more positions on the plate during the printing process of the central axis line, and furthermore, a preliminary drafting transparency is printed. When drilling the holes, center on the center position of each error confirmation marking line. a small hole for error confirmation that is set as shown in FIG. A drafting tent plate characterized in that the error in the center position of the drafting through hole and the center axis line that has lost its intersection point is determined. ．． (2) The drafting template according to claim 1, wherein the error confirmation marking line and the error confirmation small hole are perfectly circular.
