Oh, that's easy. - Load the model in AC3D - Switch to "Vertex" Mode (Press 'v' when mouse pointer is overhead one of the four views) - select the vertex that should act as the rotation center (or one of the two vertices that serve as the rotation axis) - Hit the '>' arrow left to the "move-to" fields in the left pane This fills the location fields with the coordinates of the vertex. Use X as your <x> in your animation Use Y as your <z> in your animation use Z as your <z> in your animation, just flip the sign That's it.
