Abstract
A transparent board-like digitizer is placed near a display screen. Images of the same size as that of the digitizer images entered on the digitizer are displayed on the screen. A co-ordinates standard of the digitizer is set to be identical with that of the screen. Thereby, the point indicated on the digitizer of a first cursor device is shown at a position corresponding to that of the point indicated by the cursor. The screen displays right-angle scale lines controlled by a second cursor device on the digitizer. The right-angle scale lines can carry out parallel movements and rotations on the screen. When a straight line drawing is carried out, an operator indicates two points on the digitizer by means of the first and the second cursor devices and inputs the data of such two points, whereby a straight line connecting these two points, dimension supplemental lines in parallel with the right-angle scaling lines, dimension lines extending between the two points, and a dimension figure, respectively, are displayed on the screen.
