Computer-aided design (CAD) is the use of computer systems and software to assist in the creation, modification, analysis or optimization of an engineering design. CAD software is used to increase the productivity of the designer, improve the quality of design, improve communication through documentation, and create a database for manufacturing. CAD output is often in the form of electronic files for print, manufacturing or other manufacturing processes.
CAD applications are extensively used in many specifically mechanical applications across industries, including automotive, ship building, aerospace industries, and industrial design. CAD software helps us explore ideas, visualize concepts through photorealistic renderings and movies, and simulates how the design project will perform in the real world.
Today, CAD is an essential tool in engineering, manufacturing, product design, sustainability, and even entertainment, because it helps us explore ideas, visualize concepts, develop solutions to problems, and test how the design project/product will perform in the real world.
