"Computer-aided design Computer-aided design (CAD) is the use of computer systems (or ) to aid in the creation, modification, analysis, or of a design. 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 output is often in the form of electronic files for print, machining, or other manufacturing operations. The term CADD (for ""Computer Aided Design and Drafting"") is also used. Its use in designing electronic systems is known as electronic design automation (EDA). In mechanical design it is known as"
"Computer-aided industrial design Computer Aided Industrial Design (CAID) is a subset of computer-aided design (CAD) software that can assist in creating the look-and-feel, or industrial design aspects of a product in development. CAID programs tend to provide designers with improved freedom of creativity compared to typical CAD tools. However a typical workflow may follow a simple design methodology as follows: The end result is generally a 3D model that represents the main intent of the designer had in mind for the physical product. Such models can then be saved in formats for more convenient exchange with others (such as OBJ"
"Computer-aided architectural design Computer-aided architectural design (CAAD) software programs are the repository of accurate and comprehensive records of buildings and are used by architects and architectural companies. The first program was installed back in the 1960s, to help architects save time instead of drawing their blueprints. Computer-aided design also known as CAD was originally the type of program that architects used, but since CAD couldn’t offer all the tools that architects needed to complete a project, CAAD developed as a distinct class of software. All CAD and CAAD systems employ a database with geometric and other properties of objects; they"

This is not the only definition for CAM, but it is the most common; CAM may also refer to the use of a computer to assist in all operations of a manufacturing plant, including planning, management, transportation and storage. Its primary purpose is to create a faster production process and components and tooling with more precise dimensions and material consistency, which in some cases, uses only the required amount of raw material (thus minimizing waste), while simultaneously reducing"

CAID programs tend to offer more tools that allow a designer to freely express themselves with more organic shapes and complex curves, whilst CAD software tends to be more focused on tools for the simple curves and straight lines more suitable for easy manufacturing. CAD implementations have evolved dramatically since initial 3D offerings in the 1970s, which were typically limited to producing drawings similar to hand-drafted output. Advances in programming and computer hardware,[21][22] notably solid modelling in the 1980s, have allowed more versatile applications of computers in design activities.

CAD software for mechanical design uses either vector-based graphics to depict the objects of traditional drafting, or may also produce raster graphics showing the overall appearance of designed objects. However, it involves more than just shapes. As in the manual drafting of technical and engineering drawings, the output of CAD must convey information, such as materials, processes, dimensions, and tolerances, according to application-specific conventions. CAD may be used to design curves and figures in two-dimensional (2D) space;"

Engineers primarily manufacture parts manually in the areas of applied spray coatings, finishes, and other processes that cannot economically or practically be done by a machine. Drafting is used in nearly every subdiscipline of mechanical and manufacturing engineering, and by many other branches of engineering and architecture.

For instance, some hospitals use CAD to support preventive medical check-ups in mammography (diagnosis of breast cancer), the detection of polyps in the colon, and lung cancer.
