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.
