From the early 1960s to 2021, several CAD companies have come on the scene. The CAD industry has been prosperous thanks to this healthy competition. “Big Five” CAD vendors in the 1970s and 1980s, Applicon, Auto-trol, Calma, Computervision, and Intergraph, also produced amazing CAD software in different fields, making the CAD industry more competitive than ever before. This product was later named the Electronic Drafting Machine (EDM). In the early 1960s, the Itek Corporation intended to develop the first commercial CAD product that enables users to create, display, and edit simple diagrams with a photoelectric light pen. Even though their work didn’t end up with a commercial product, other CAD players were committed to this design revolution. After that, at the Lincoln Lab, Sutherland’s work was expanded upon by Tim Johnson who introduced three-dimensional data models and graphic images to SKETCHPAD. In 1961, Ivan Sutherland developed SKETCHPAD, universally known as the first interactive graphic system for engineering design and drafting. The history of CAD software can date back to the early 1960s. The quality of design and communication is also improved greatly. Therefore, far fewer manual efforts are needed for massive and complicated design tasks within a limited time. As its name suggests, the creation, modification, analysis, and optimization of a design can be aided by computers. ZWCAD can facilitate automotive designĬAD is short for Computer-Aided Design.
