Designing boxes in Inventor 2010

i'm a sophomore at uva, and we're just starting to use inventor to make worthless widgets, so i figured i'd try making some boxes. It's pretty easy obviously, the only problem is I can't figure out how to get the drawing to show the different extruded planes as "boards" as we would see them in person, i.e. my box here looks like one solid chunk instead of separate pieces glued together. How do I show ALL the edges of each "board?" without having them blend together like this: (referring to the isometric view in the upper right.
