Abstract
Automatic and rapid transfer of CAD data among differentCAD systems or engineering applications is of crucial importancefor the acceleration of the product development processes. Geometric models generated by CAD systems often require multipleediting and adjustment within the receiving system. The ma jorreason for this is that models generated by CAD systems oftencontain errors in their representation, such as cracks, duplication or overlaps. Such errors often hamper further processinglike finite element analysis, rapid prototyping, etc.In our previous work the concept of virtual topology was introduced which permits construction of valid topological modelswithout prior geometrical correction. The virtual B-Rep provides a consistent geometric description of the model which issuffcient for many engineering applications. However providingan exact geometric description of the model if often desirable forfurther processing purposes.In this work a new algorithm for repair of CAD models geometry is described. The algorithm is based on the model topology provided by the virtual B-Rep. The generated geometricdescription consists of the topological connectivity informationon the model and of a triangular conformal faceting of the modelfaces envelope.
