Computer Graphics and Design Automation: Continued Synergy or a Parting of Ways?
From its very beginning, computer graphics has had a significant influence on the evolution of engineering design automation. Ivan Sutherland’s MIT thesis, “Sketchpad” in 1963 laid the foundation for interactively creating and manipulating line geometry on a computer generated graphical display. This capability lead to the interactive generation of engineering drawings, the first successful commercial venture in computer graphics. From a design point of view, the CAD system simply automated the human process of generating drawings, and only indirectly improved the process of design. Furthermore, the lines drawn on the screen had no associativity, no concept of a surface or volume. In effect, the computer graphics system was just a glorified plotting capability.
