The first true CAD software was called Sketchpad, developed by Ivan Sutherland in the early 1960s as part of his PhD thesis at MIT (Massachusetts Institute of Technology).
What was CAD first used for?
The first commercial applications of CAD were in large companies within the automotive and aerospace industries, as well as in electronics. This was because only large corporations could afford the computers capable of performing the necessary calculations.
How is CAD created?
The beginnings of CAD can be traced to the year 1957, when Dr. Patrick J. Hanratty developed PRONTO, the first commercial numerical-control programming system. In 1960, Ivan Sutherland MIT’s Lincoln Laboratory created SKETCHPAD, which demonstrated the basic principles and feasibility of computer technical drawing.
Who influenced CAD?
The Pioneers of CAD
In 1961, Patrick Hanratty joined General Motors Research Laboratories where he helped develop DAC, (Design Automated by Computer), the first CAD system to use interactive graphics. Ivan Sutherland broke new ground in 3D computer modeling and visual simulation, which is the basis for CAD.
