Computer-aided design (CAD) is the use of computer-based software to aid in design processes. CAD software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to create a database for manufacturing. CAD is one part of the whole digital product development (DPD) activity within the product lifecycle management (PLM) processes, and as such is used in many ways depending on the profession of the user and the type of software in question. CAD software is used heavily within various architecture, arts, and engineering projects. CAD use cases are specific to industry and job functions. Professions that use CAD tools include architects, engineers, city planners, graphic designers, animation illustrators, drafters, fashion designers, interior designers, exterior designers, game designers, product designers, and industrial designers.
CAD enables the development, modification, and optimization of the design process. Engineers can make more accurate representations and modify them easily to improve design quality. The software also takes into account how various materials interact, which is especially relevant as more details are added to drawings by subcontractors. Effective utilization of all information can help increase productivity. CAD helps enable designers to consider electricity, plumbing, and other elements to create a more comprehensive design. Ultimately, this translates to fewer work changes and fewer surprises during construction.
CAD has changed manufacturing as we know it. It has streamlined the design of products, as well as contributed to higher-quality goods. Further, CAD has enabled manufacturing teams to collaborate and communicate on designs more easily. Today, computer-aided design (and specifically CAD software) is utilized across a wide variety of industries and fields, including electrical engineering, industrial engineering, structural engineering, architecture, and interior design.
