Abstract
A contract estimating system includes a digitizer ruler divided into a plurality of equally spaced increments. The ruler generates an output signal representing the distance along the ruler at a point touched by a hand held probe. A digitizer board carries a menu thereon including a plurality of indicia such as words, pictures and numbers representing different component parts and sizes and scale factors and generates an output signal corresponding to one of the indicia when touched by the probe. A computer automatically counts the number of each size component part and calculates the total length of pipes and similar components measured by the ruler. The results calculated by the computer can be displayed on a CRT and/or printed on a printer.
