Abstract: PURPOSE:To enable the shape of all of the constituents to be changed by adding information with respect to two reference points and a cutting line to change a graphic on a component graphic, supplying two arranging points corresponding to each of the reference points, and extending a line segment crossing with the cutting line. CONSTITUTION:An original component graphic is constituted of the line segment which constitutes the graphic, the two reference points 1 and 2, and one cutting line 3, and the line segments 4 and 5 crossing with the cutting line 3 are set as the shape to be changed. Two arranging points 1' and 2' to arranged the component are inputted, and the expansion quantities of the segments 4 and 5 are found from a distance between the two points, and the shape of the graphic can be decided. The shape changes only at a part where the line segment crosses with the cutting line, and other parts remain unchanged. In such a way, it is possible to define a component with variable shape only by adding a few amount of information on the shape of the component, and since it is not required to add the information on the part remaining unchanged, the amount of information for the whole of the component can be reduced.
