Computer-aided design (CAD) refers to computers being used to assist the design process in all sorts of industries. With CAD software, it’s possible to build an entire model in an imaginary space, letting you visualize properties like height, width, distance, material, or color before the model is used for a particular application.
It was 1962 when the computer scientist Ivan Sutherland created the first computer graphic program, known as “SketchPad”, which allowed people to write or draw simple figures directly on a screen with the help of a special pencil. This marked the start of all future CAD software.
At first, CAD was used only for research purposes, but in the 1970s, big automotive and aerospace companies started developing their own software, expanding its applications to other industries in the 1980s. It wasn’t until the 1990s that tools like CATIA and AutoCAD were born, making it possible to be used in many professional sectors.
