Abstract

PURPOSE:To prevent an operator from erroneously recognizing information by displaying elements constituting a dimension inquired by means of an interrupting processing and prepared based on a calculation result, and setting a dimension line display ratio without depending on the enlargement ratio of a visual display device. CONSTITUTION:When an inquiring means 2 inquires the dimension by the interrupting processing, a coordinate read means 13 reads the coordinates of the elements constituting an instructed graphic, a calculating means 14 calculates the dimension value corresponding to a request based on the coordinates of the read elements, and a preparing means 15 prepares the dimension line based on the calculation result. A display ratio setting means 16 sets the display ratio of the dimension line so as not to depend on the enlargement ratio of the visual display device 23, and a display means 17 displays the elements constituting the prepared dimension line on the visual display device 23. Thus the dimension can be easily obtained by irreducibly minimum operations, and the operator can recognize which dimension it indicates without an error.
