Where did CAD come from?
The term “Computer Aided Design” (CAD) emerged in the 1950s and is commonly credited to Douglas Ross, a computer scientist who was working at MIT when the acronym was coined.
Why was CAD made?
The development of the sketchpad system revolutionized design because it made creating drawings and interactively moving and changing objects on a computer screen possible. The term CAD started to appear with the word ‘design’ because it went beyond basic drafting concepts.
How is CAD created?
The beginnings of CAD can be traced to the year 1957, when Dr. Patrick J. Hanratty developed PRONTO, the first commercial numerical-control programming system. In 1960, Ivan Sutherland MIT’s Lincoln Laboratory created SKETCHPAD, which demonstrated the basic principles and feasibility of computer technical drawing.
What was used before CAD?
Before the advent of AutoCAD and other drafting software, engineering drawings were made on sheets of large paper using drawing boards. Many types of equipment was required to complete a given drawing, such as drawing board, different grade pencils, Erasers T-squares, Set square etc.
