CAD systems are widely used in industry. They are used in many applications in mechanical engineering, in plant design and in the electrical and electronics industries. Much of the system functionality is specific to the particular application. The functionality of a CAD system characterises the quality and quantity of input, processing and output functions it offers its users, both to support individual design activities, as well as to support the design processes of their organisations.
