16. Bottomline • ‘DESIGNERS’ may have been a single person or a team of few • ‘DESIGNERS ’ were ‘multi-faceted’ – they practised many other avocations out of ‘Choice’ • Design HAD TO BECOMMUNICATEDto those building it (‘MANUFACTURERS’) • COMMUNICATION could have been possible only through ‘SKETCHES’ or ‘DRAWINGS’

18. Inventor of ‘descriptive geometry’ Pictures, sketches were used to communicate but didn’t have any uniformity One could draw figures in various ways Architects, builders, engineers, designers had difficulty in understanding figures 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 Gaspard Monge, 1746-1818 Engineer in French Military OBJECTIVE: To Learn TECHNICAL DRAWING in THEORY and PRACTICE using drafting tools and free hand sketches
