Abstract: PROBLEM TO BE SOLVED: To unify design and work, and realize an automatic working plan by a computer to shorten a development period for a product, by automatically obtaining data concerning a working plan from three-dimensional shape data obtained from a CAD system, by a computer. SOLUTION: At first, shape data from a CAD system are received in an input part 10, and then a surface and an angle are extracted from the shape data to constitute the linking graph of the surface and the angle (the linking graph constitution 21 of the surface and the angle) in a processing part 20, and cutting point search and a subordinative graph are created (cutting point search and subordinate graph creation 22) by using the linking graph of the surface and the angle, to extract the fearure shape for the working plan by the linking graph of the surface and the angle, the cutting point, and the subordinative graph (extraction 23 for the feature shape), thereby outputting the feature shape from an output part 30.
