The term computer-aided construction or English computer Aided Design (CAD) [] a kind designates "electronic board ".

With CAD programs one does not only provide technical designs. With the programs first of all three-dimensional volume models are provided. From this two or three-dimensional designs and visualizations of the objects even moved can be derived. CAD software is used in all specialist areas, in which constructions are developed: for example in the equipment construction, mechanical engineering, shipbuilding and also in architecture and in the building industry.

With the volume models one can accomplish most diverse Simulationen with the help of special software, for example Belastungssimulationen (finite element method) with construction units, Lichtsimulationen or Simulationen of the interior climate with buildings, (wind or waves), Crashsimulationen in the construction of vehicles and Simulationen of different manufacturing methods (e.g. Injection moulding).

One can use the volume models still for many other things such as strength calculations, generativer manufacturing methods and naturally also in the CNC manufacturing with machines. CAD is also a component of the computer-integrated production (CIM), with which the draft the manufacturing follows.

Modern programs are based on object-oriented data bases. Each component of the Design consists of one or more objects by programming. Changes and specifications are the parameters of the objects. Parameters can be based on relations with other Design aspects and make versions and variations of the same Design available. Object-oriented data bases permit optimal reusability of Design components, the optimum recording as well as the possibility of fast adaptation to the intention of the designer. Together these advantages result in object-oriented parametric modelling "State OF the kind".
