This is where animation features, such as you get in MAX, really come in handy. There you can set the hinge axis exactly where you need it to be, then set the animation to rotate it back and forth, and be able to "take notes" on the needed angles, not to mention the timing of multiple systems (e.g., making sure the doors get far enough open before the gear and wheels start rotating out of the bay).
