In my version of Mathematica (8.0.1 for OS X) the boxes stay the same shape when I rotate the graphs in your examples, but you could try setting BoxRatios->{1,1,1} if you want the bounding box to be a cube. To keep the size of the graph the same when rotating it you could try setting SphericalRegion->True. Heike On 14 Sep 2011, at 11:12, Christopher O.
