It involves the integration of computer science methods and engineering sciences in a computer-based system providing a data base, a program library and a communication subsystem.
CAD implies by definition that the computer in not used when the designer is most effective and vice versa.
A CAD-system contains hardware and software components, which are effectively integrated into one system. The CAD hardware typically includes the computer, one or more graphic display terminal, keyboards and other peripheral equipment.
The CAD software consists of the computer programs to implement computer graphics on the system plus application programs to facilitate the engineering functions of the user company.
By implementing CAD, it will increase productivity of the designer through the visualization of the product and its component, sub-assemblies and related parts and by reducing the time necessary for the development of a conceptual design analysis and documentation.
By using CAD design error can be eliminated at the early stages of design.
Today most CAD system only supports the detailing process with tbe goal of generating a finished technical documentation of the technical solution which can be used for manufacturing and assembly.
