The article “Computing in Architectural Design” by Yehuda Kalay provides a very detailed description of the history of the use of computers to aid in design dating back to the 1950s. Beginning with Ivan Sutherland in the early 1960s and his development of the “light-pen” and sketchpad, computer aided design has come an extremely long way. The concept for this first system was one in which the draftsman would draw using the light-pen onto a complex display known as a sketchpad, where the computer would process what has been drawn by hand and convert it to math and a graphed set of numbers. The article follows the timelines through the decades describing high points of noteworthy breakthroughs of CAD technology. Some lessons I took from this article are that technology will never stop getting faster and smaller, and by the time a new precedent is set in CAD, there is already something more innovative in the works. The most important point I took from this article re-enforces the thinking I have been talking about for years: no matter how far technology advances, the most precious resource in the world will always be the creative thought processes of the human mind.
