The specific embodiment

See also accompanying drawing.Fig. 1 is how much mappings of this reality invention schematic diagram, and wherein geometry coordinate machine is by geometry coordinate machine 1, bar ruler 2, radius hole 2-2, protractor 3, center of circle 3-1, metric scale 4, working edge 4-2, foot rule 5, foot rule working edge 5-2, chi 6, ruler 7, mapping groove 8, numeral 9, scale 10, material-saving hole 11 constitutes, and it is characterized in that the center of circle 3-1 of the protractor 3 of described geometry coordinate machine 1, with the metric scale initial point 4-1 of metric scale 4 at a point; The zero degree initial line of protractor 3 and the working edge 4-2 of metric scale 4 be at a line, geometry coordinate machine 1 range structure changeable.

Metric scale 4, foot rule 5 pass protractor 3 the zero degree initial line up and down to center of circle 3-1, protractor 3 has adaptive change with metric scale 4 and foot rule 5 on numeral, scale, foot rule initial point 5-1 and metric scale initial point 4-1 coexist on the longitudinal axis, and center of circle 3-1 has solid and hollow form setting.

The radius hole 2-2 of described ruler 7 is distributed in metric scale 4, on foot rule 5 and chi 6 the scale, arranges out the radius ordinal number.The radius value of radius hole 2-2 is provided with by the scale metering unit amount of determining on each yardstick, metric scale 4 with 0.25,0.5,0.75 and 1 millimeter radius unit, the numerical value that numerical value is millimeter is extended in the back, arrange out the diameter precision of drawing and reach 0.5 millimeter, the result of 1 millimeter ordinal number diameter, when the numerical value of mapping radius value surpasses in numeral 9, obtain on the scale 10, the size of radius distance value is to be arranged on metric scale 4, foot rule 5,2-2 hole, the radius hole bit architecture of chi 6 digital high scales, indicate the number of division word reduction general designation on ruler and the protractor, the radius hole 2-2 of ruler 7 extends row's example in the positive negative direction of chi initial point.
