ABSTRACT
Engineers communicate with mathematical formulas and blueprints (drawings). Since the early days of humans, mathematical formulas have been improved and have stood the test of time. We have indeed learned how to communicate with numbers at a very sophisticated level. However, the second form of communication for engineers-blueprints (drawings)—has been drastically changed because of different interpretations that humans put on the pictures. The mathematical foundation of this change started in the late eighteenth century when Gaspard Monge solved the problem of “two-dimensional representation of three-dimensional objects,” known as descriptive geometry. With this breakthrough, engineers were able to provide a method to create auxiliary views projected with right angles and work lines to yield three basic solutions:
• True lengths of lines • Point view or end view of a line • True shape of a plane or surface
Because of this breakthrough, in 1994 the manufacturing community decided to do something about this confusion and developed an international language that presents their product innovations.
