39. Gaspard Monge, 1746-1818 Engineer in French Military Inventor of ‘descriptive geometry’ Pictures, sketches were used to communicate but didn’t have any uniformity Architects, builders, engineers, designers had difficulty in understanding figures One could draw figures in various ways Monge formalized the TECHNICAL drawings, what we know as ORTHOGRAPHIC PROJECTIONS. The scheme was quickly adopted by army Engineers, and after the war, it was accepted worldwide and formed the back bone for INDUSTRIAL REVOLUTION OBJECTIVE: To Learn TECHNICAL DRAWING in THEORY and PRACTICE using drafting tools and free hand sketches
