The paper presents a technique for correcting discontinuites (holes, overlapping surfaces, and intersecting surfaces) in CAD data. The technique approximates faulty geometries by several new B-spline surfaces which match properly. Each B-spline surface is constructed from four user-defined boundary curves.
