<p>PURPOSE:To easily correct a graphic element by specifying a prescribed graphic element, changing the color or a kind of line of the specified element to plot a graphic by the 1st format, and changing the color or the kind of line of a reference element necessary for the definition of the graphic element to draw the graphic by the 2nd format. CONSTITUTION:Circles C1, C2 and a straight line S1 are defined by quoting a graphic element on a tablet device 108, a keyboard 105 or a CRT106 and a yellow line e.g. is plotted on the CRT106. In case of changing the circle C2, a 'element correction' item 5 is picked up from a tablet menu list 108b and a graphic cursor G is set up to the circle C2 to be the element to be changed on the CRT106 to pick up the circle C2. Thus, the circle C2 is drawn by a different kind of line and a different color, a 1st reference element necessary for the definition of the circle C2 is plotted by another line with a different line short and a different color and the 2nd reference element of the circle C2 is plotted by another line with a different kind of line and a different color. This constitution makes it possible to easily correct the graphic element.</p> |
