                          CYL4, XCENTER, YCENTER, RAD1
                          CYL4, X coord for the center, Y coord for the center, radius; there-
                      fore, the command line for this circle is CYL4,80,50,50.
                          Now create a second and third circle for the left-hand side using the
                      following dimensions:

                                   Parameter      Circle 2    Circle 3
                                 XCENTER        0           0
                                 YCENTER        20          80
                                 RADIUS         20          20

                          Create a rectangle on the left hand end to fill the gap between the two
                      small circles.

                          Your screen should now look like the following:



























                          Boolean Operations: Addition
                          We now want to add these five discrete areas together to form one
                      area. To perform the Boolean operation, from the Preprocessor menu,
                      select:
