PURPOSE:To easily draw a ruled line, whose length is desired by a user, by urging the user to instruct the length and direction to draw the ruled line when drawing the ruled line. CONSTITUTION:When a 'ruled line' function key is pressed from an input device 1 by the user, a controller 3 is turned to a ruled line function mode, and a picture urging the start point instruction of the desired ruled line to be drawn and the line type instruction to the user is displayed on a display device 2. When the user moves a cursor to a desired position to draw the ruled line and selects a real line, dotted line or broken line by using a ten-key, a picture urging the instruction for the length of the desired ruled line to be drawn to the user is displayed. When the user numerically inputs the length of the desired ruled line to be drawn and presses an execution key, a picture urging the instruction for the direction to draw the ruled line from the instructed position of the start point to the user is displayed. When the user instructs the direction to draw the ruled line, the ruled line instructed from the instructed start point position by the user is displayed on a screen. |
