What was the first commercial CAD software system?
The first commercial CAD software system was Sketchpad, developed in 1963 by Ivan Sutherland. While not a commercial product, it laid the foundation for computer-aided design.
The first widely used commercial CAD software system was DAC-1 (Design Augmented by Computer), introduced by General Motors in collaboration with IBM in the early 1960s. However, AutoCAD, launched in 1982 by Autodesk, became the first highly successful commercial CAD software accessible to a broad range of industries and users, marking the start of CAD’s widespread adoption.
