Simple 2d cad software free manual#
Used by engineers, architects, and construction managers, CAD has replaced manual drafting. With a name change to AD-2000 along with more machining and surfacing capabilities, the program became a hit. Hanratty upgraded ADAM over time, enabling it to run on 16-bit, and later 32-bit computers. It was described as the “first commercially available integrated, interactive graphics design, drafting, and manufacturing system.” Approximately nine in 10 of CAD programs find their roots in ADAM. In 1971, Hanratty developed a program called ADAM. Just two years later, in 1963, Ivan Sutherland designed a system that “broke new ground in 3D computer modeling and visual simulation, which is the basis for CAD.” Sutherland called his program Sketchpad, and explained it “let designers use a light pen to create engineering drawings directly on a CRT.” While working for General Electric, Hanratty developed a program he called DAC, the first system which used interactive graphics and a numerical control programming system. The origins of CAD trace back to the early 60s and Patrick Hanratty and Ivan Sutherland. This has always been the case, yet with the introduction of CAD, technology’s role in the industry and the impact it has on the job have both grown. Although all these constitute part of the job, construction is in many ways a tech job. Perhaps this person is putting up drywall, hammering nails, laying flooring, or even having lunch high above the ground, evoking the iconic Lunch Atop a Skyscraper photograph.
When most people envision a construction worker, they see a person at a construction site wearing a hard hat and a safety vest.
