<p>PURPOSE:To easily and quickly select the command of a lower hierarchy in a single operation of a CAD device without breaking a characteristic command hierarchy. CONSTITUTION:The CAD device consists of a keyboard 3 which inputs a character, a coordinate or an angle, etc., a pointing device 4 which directly selects the coordinates and the element, and a display device 6 which displays the character and the coordinates inputted from the device 4. Then the lower command hierarchies are successively displayed in real time with an instruction of the device 4. Thus the final object command is directly decided.</p> |
