ABSTRACT:
A method of the present invention includes storing in a memory first data including coordinate values of straight lines forming the drawing and first color code and second data including a dimensional value between two straight lines and two coordinate values of the two straight lines; supplying the first data and second data to a display to display the drawing and dimensional values on a display screen; changing, in response to a selection of one straight line, first color code of the selected straight line to a predetermined color code, and changing first color codes of straight lines parallel to the selected straight line to second color code; reading second data including two coordinate values one of which is equal to a coordinate value of the selected straight line; and changing the second color code of first data, which includes a coordinate value equal to the other of the two coordinate values of the read second value and the second color code, to the first color code.
