The configuration or construction of systems vary depending on the way the systems are to be used, i.e., displaying solid shapes in three dimensions, processing the solid shapes, or obtaining their volume or center of gravity.

E-Unification via Transformations,lar, for verifying products or determining whether their parts can actually be used, by using computers. This chapter explains the outline of CAD/CAM/CAE systems and how they have been developed. As these systems must be organized to design and manufacture products efficiently, the present condition of the systems is also described.

Front Matterraus abgeleitete Begriff ’Cyberspace’ transportiert die Hoffnung, „die ultimative Ratio der Mensch-Maschine-Kommunikation zu erreichen" (ders., op. cit., 6). Der technische Kernprozess ist dabei die Manipulation und Visualisierung komplexer Daten, unterstützt durch akustische und taktile Sinnesreize
