Here's another question. I just cut the button holes into my remote control top half. And I see in the feature tree that the button hole sketch and the Extruded Cut are now "nested" together in a sort of association. Now I need to make the buttons. Which procedure is considered "best practice" in SolidWorks? A) using the same sketch associated with the Extruded Cut, or B) duplicate/recreate the sketch for separate use with the Extruded Boss/Base function?

If the correct answer is to duplicate the sketch, how would I do this? Thanks-
