The recent years involved a great increase in the use of CAD-Systems by industrial organizations for the development and manufacturing processes of technical products. In the beginning the creation of technical drawings was the main task of those systems. Meanwhile they are used to support the development and manufacturing process with several different applications. Therefore a more precise description of the technical product meeting the technical requirements of the specific application became imperative. This fact as well as economic and regional aspects caused the development of several different and mostly incompatible CAD-Systems being more or less adjusted to a specific application. The incompatibility is manifested — leaving out differences in hardware configurations — by different file formats, partially different information contents and different ways to describe the information contents. Those differences result from efforts to optimize the software with regard to the need of storage, running time of the functions of the system and the integrity of its data.
