PURPOSE:To easily define a correcting shape from an already defined shape by surrounding an element, which is moved to a shape to be drawn, with a rectangle, defining an element crossing the line of the rectangle as a stretching element, and inputting a moving amount and a moving direction. CONSTITUTION:A processor (CPU) 10 displays the shape to be corrected on the screen of a display device 14, designates more than one elements to be moved in this shape by surrounding them with the rectangle and moves the moving elements in the rectangle only for the set amount by setting the moving direction and the moving amount. In this case, there is an intersection between the moving element designated by the rectangle and the element crossing the line of the rectangle, and when the moving element is moved, the intersection is moved as well. Then, an intersection is calculated between the element crossing the line of the rectangle and the adjacent moved element any by stretching the element crossing the line of the rectangle to the intersection close to the original intersection, the corrected shape is obtained. Thus, the already defined shape is corrected, and the new corrected shape can be easily defined. |
