History of National CAD Day
The history of CAD dates back to the 1950s when early computer graphics and numerical control systems were developed. Patrick J. Hanratty’s creation of PRONTO in 1957 marked a significant milestone in commercial numerical-control programming systems. Later advancements like Ivan Sutherland’s Sketchpad in 1963 laid the foundation for modern CAD systems. Over the decades, CAD evolved from 2D drafting tools to sophisticated 3D modeling software used across various industries today.
