Modern engineering design and drafting can be traced back to the development of descriptive geometry in the 16th and 17th centuries.
Drafting methods improved with the introduction of drafting machines, but the creation of engineering drawings changed very little until after World War II. During the war, considerable work was done in the development of real-time computing, particularly at MIT, and by the s there were dozens of people working on numerical control of machine tools and automating engineering design.
CAD arrival increased the productivity of designers and improved the quality of design amongst other benefits. The software CAD is used to support both engineers and designers across a range of industries, including architecture, automotive and aviation.
But what is the history of these two different processes? How did they begin, evolve and combine? And what has their pairing allowed designers and manufacturers to do? Initially used by Douglas T. Ross, a researcher at the Massachusetts Institute of Technology MIT , was working with military radar technology and computer display systems. Patrick J. Most design at this time was still being done with pencil and paper.
According to Tony Rogers, president of design shop Creative Mechanisms ,. In 2D CAD you were drawing the same way you always had. It [2D CAD] took almost the same amount of time as doing 2D drawings by hand with the big difference being that changes were much much faster and easier to make.
