<p>PROBLEM TO BE SOLVED: To simplify a procedure and to shorten manhour in the case of collectively preparing blurred/offset curved surfaces for die shape data. SOLUTION: Curved surfaces in a range to be offset which is shown by slashes and curved surfaces in a range to be blurred which is shown by horizontal lines are segmented from plural curved surfaces Sa1, Sa2, Sf1, Sf2, Sf3, S1, S2. Blurring and offsetting processing based on a reference curve Lg is applied to the constitutional points P of curve surfaces respectively included in the range to be offset and the range to be blurred and a new curved surface is prepared based on the blurring and offsetting processing.</p> |
