    Computer integrated manufacturing requires new software structures to enable free interaction between computer aided design, planning, production and quality control. The challenge of information technology in the factory has led to a new view on productgestaltung. Especially the new possibilities of geometric modelling and their applications which make use of features, product models and knowledge-based modules enable the merging of design and manufacturing.

    Limited system consistency in handling 2-D and 3-D modelers is among the serious critical aspects of modern-day CAD systems. The reconstruction method enables straightforward and familiar 2-D input methods for orthogonal views to be conveniently interlinked with the well-known virtues of solid modelling. One problem associated with his technique is, however, the unavoidable generation of excess 3-D elements resulting from projections and only barely identifiable using algorithmic techniques. An approach is described which, with the aid of knowledge-based methods, enables a far-reaching automatic reconstruction of volume models and thus helps to reduce the problem of generating inconsistent models.
