Exactly in 1963, he was presented the program Sketchpad written by Ivan Sutherland for which he received the Turing Award in 1988. Sketchpad is considered the ancestor of the modern computer-aided design (CAD) as well as a breakthrough in the development of computer graphics. Ivan Sutherland showed that computer graphics can be used both for artistic and technical. Currently, a group of CAD software is so extensive that looks every technical field. Personally, I had to deal with many such programs. I recommend reading them, many of them created under the GNU for the supporters of free software. It supported more than 50 years of tradition.
CAD application of computer hardware and software technical design. CAD methodology is used among others in mechanical engineering, electrical, construction. Symptomatic CAD is digital geometric modeling to develop storage product design.
