332 CHAPTER 10 USIng EqUATIOnS

7. Click Rebuild, press Ctrl+B or Ctrl+Q to rebuild the model, and observe whether any
update takes place.
8. Rename the 6.00-inch dimension for the height of the revolved feature to DomeHt.
9. Create a second equation that drives the DomeHt dimension at the current ratio of the
height to the radius.
a. In the Equations dialog box, create a global variable called Ratio = 6/3.6 (1.66667).
b. Create the equation. The equation takes the form of DomeHt = (Ratio) × CapRad. You
can use the drop-down list under the calculator pad to select the Ratio variable
from the list.
10. Use a variable to make the radii of Fillet1 and Fillet2 the same.
11. Double-click the Revolve feature. Change the CapRad dimension to 5 and rebuild. You
should observe three feet. Change it again to 6, and you should see four feet.
12. Give the part a new name, including your initials or the date, and save and close it. See
Figure 10.18.
