"Industrial drawing" or "technical drawing", whether manual or computer-aided (CAD, CAM...), is first and foremost a language or graphic communication tool with precise rules. This language, largely standardized internationally (ISO: International Standard Organization), can be considered a universal language used in the same way all over the world. Industrial drawing is used by technicians, engineers, and designers to communicate from the initial idea of a product to its design and production. All products, machines and Various systems are first designed and defined graphically before considering their manufacturing.
