Sure, you are correct. Since AABB is not supported any more (but it still works) all c_ instructions in Acknex use ellipsoid shape. About the demo, unfortunately it does not provide a real AABB alternative, but just a fake one made out with ellipsoid shapes. Sorry for describing it wrong in my posts above.

No, I've made some tests. c_move and c_rotate use a box shape, c_trace (with USE_BOX) uses really an ellipsoid shape.
