INTERSECTING FEATURES EXTRACTION FROM 2D ORTHOGRAPHIC PROJECTIONS

This paper describes a new approach to solve the problem of intersecti ng features extraction. Feature extraction is important from several s tandpoints-automated process planning, NC machining, automated assembl y and virtual prototyping. Feature extraction reported in the literatu re indicates limited success mostly in extracting a partial List of no n-intersecting features. There has not been much success in the extrac tion of intersecting features. Techniques must continue to be develope d to extract intersecting features and identify them as combinations o f standard features. Our methods of intersecting feature extraction ar e different from current methods in that they operate on 2D CAD as inp ut data, thus obviating analysis in complex 3D space.
