The use of computers to facilitate or assist design has been around since the mid-20th century. The term “Computer Aided Design” (CAD) emerged in the 1950s and is commonly credited to Douglas Ross, a computer scientist who was working at MIT when the acronym was coined.

How was CAD invented?

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.

What type of software is AutoCAD?

AutoCAD® is computer-aided design (CAD) software that architects, engineers, and construction professionals rely on to create precise 2D and 3D drawings.

Why is AutoCAD so expensive?
