The geometric representation of man-made objects has always been considered essential for their design and construction. It is inconceivable that cathedrals, catapults, caravels and clockworks could have reached their level of perfection without the concurrent development of graphic tools as the lingua franca between designers, clients (“end-users”), and artisans. Drafting conventions were gradually refined and formalized according to the requirements of different disciplines (sheet metal, piping, trusses, part and assembly drawings, renderings). Till recently, “mechanical drawing” formed an important component of engineering and architectural education.
