<p>A predetermined menu item is picked up from a menu table (108b) to designate a method of defining a figure component, and a predetermined figure component described on a display screen (106) is picked up. A processor (102) defines a new figure component using the method of defining picked figure component and the picked figure component, and then defines the shape of a part using the picked figure component in the order of moving the tool after the definition of all figure components has been completed. The processor expresses the figure component and the shape of part in a first form using an automatic programming language as defined and stores them in a memory area (103b), and it further expresses the points of the figure component using coordinate values, expresses a straight line using coordinate values of two points, expresses a circle using center coordinate values and arc radius, and stores them in a memory region (103c). Upon request for outputting the shape of a part, the processor (102) produces the figure component and the shape of a part in the automatic programming language using the first form, and executes the processing using the second form for discriminating the figure component designated by a graphic cursor or for displaying the figure.</p> |
