The Pioneering Era: Birth of CAD Drafting
The inception of CAD drafting can be traced back to the early 1960s when Ivan Sutherland presented the revolutionary “Sketchpad” – the first computer program to enable graphical interaction with a computer. This milestone laid the foundation for the future of CAD. The initial stages were rather rudimentary, involving vector-based graphics and limited capabilities. However, the seed of innovation had been planted.
