Not long after, Ivan Sutherland developed Sketchpad in 1963 as part of his thesis at MIT-titled ‘Sketchpad, A Man-Machine Graphical Communication System’. In fact, some industry analysts estimate that 70% of all 3D mechanical CAD/CAM systems available today can trace their roots back to Hanratty’s original code. Patrick Hanratty, “the father of CAD/CAM”, developed PRONTO (Program for Numerical Tooling Operations) the first CNC programming system, in 1957. Scan2CAD has put together a complete guide covering the beginnings of CAD in the 1950s, how CAD evolved after 1982, and what the future might hold for CAD.ĭuring World War II, computing underwent a lot of development. If, however, you’re not familiar with the history of CAD, you’re in luck. As such, CAD has had a long and rich history that spans back decades. While it might be tempting to think of Computer Aided Design as a relatively recent innovation, most CAD programs we use today can actually be traced back to work begun over 50 years ago.
