When was the first CAD program created and who created it?

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.

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 was used before CAD?

Before the advent of AutoCAD and other drafting software, engineering drawings were made on sheets of large paper using drawing boards. Many types of equipment was required to complete a given drawing, such as drawing board, different grade pencils, Erasers T-squares, Set square etc.
