This paper addresses the problem of CAD geometric model pre-processing, known as
CAD repair. Three main components of the
CAD model repair: global geometric continuity of the boundary, topological
validity and model preparation are discussed.
General definition and classification of CAD errors for geometric models, using
the Boundary REPresentation (BREP) are given.
Methods, invariant from the specific software implementation and algorithms of
the CAD repair for Finite Element type
downstream applications are discussed. The results of methods realization in the
prototype CAD repair module are provided
