Abstract

Shape data relative to a hemmed edge in view of production technique requirements is added to shape data relative to a design surface using a CAD system. Curvatures of curved lines, curvatures of curved surfaces, offsets and distances between shape surfaces, and angles between shape surfaces of the shape data are analyzed and verified.
