Well, I'm not an expert in boxes, I couldn't duplicate your box (nor surprising though). Just in case you haven't already tried this, there's good info in the help manual. You can go to help above and click on manual (it's online), click on index and it's listed first, 3D boxes. Basically using the Shift or Ctrl key controls much of it. Oddly, I wasn't able to type in the angles info, not sure why.
