PPROBLEM TO BE SOLVED: To easily decrease fine segment parts leading to any adverse influence on working. PSOLUTION: This CAD/CAM device is provided with a procedure(step S1) for storing an outline shape in which a plurality of continuous segments are formed by matching start and end points, and an edit procedure (step S3) for reading the stored outline shape, and for, when one discontinuous fine segment exists in the outline shape, erasing the fine segment, and for extending segments before and after the fine segment to the direction of the erased section, and for extending it to the intersection of the both segments to reform the outline shape.
