Fill Shade
      When this command is selected, a submenu is activated that allows 
 you to select the shading of the interior of an object. The options 
 available on this submenu range from 0% shading to 10% shading in 
 increments of 10%. A check mark is placed next to the option that is 
 currently in effect. 
 Alternatively, you can select Other from this submenu. When this is 
 done, a dialog box appears that allows you to select shading in the 
 range of 0 to 100 percent in increments of 1 percent.
