ABSTRACT:
A method for displaying drawings with a CAD system. The CAD system includes a drawing storage unit which stores a plurality of drawings, a display apparatus and a display control unit which causes a respective drawing to be retrieved from the drawing storage unit and displayed on the display apparatus. Each drawing stored in the drawing storage unit includes at least one graphic form, there being a plurality of different types of graphic forms and predetermined reduction rules correspond, respectively, to each type of graphic form. The method includes the steps of (a) reading a respective drawing from the drawing storage unit; (b) storing the respective drawing in the display control unit; (c) reducing each graphic form of the drawing in accordance with the reduction rules corresponding to the respective graphic form; and (d) displaying the respective drawing on the display apparatus with the graphic forms of the drawing being reduced in accordance with the corresponding reduction rules.
