The basic language of all engineering activities is represented, in the majority of cases, by design processes that involve the engineer in two distinct activities: modeling and communication. In areas such as systems design and analysis, industrial plants and processes, which are typical fields of automotive engineering, the engineer uses technical drawings in order to identify construction solutions, carry out design calculations, and perform a technical-economic comparative analysis of the various solutions. In this sense, technical drawing is not a merely graphical exercise, but becomes a synthesis of the engineer’s expertise about a product which must respect economic, manufacturing and functional specifications. Today technical design is a document to communicate all information of an industrial component with the main objective of its manufacturing.
