Just playing around with 3D objects and the extrusion tool in Xtreme and was wondering, when you've created your 3D extrusion, how do you control its rotation (besides simply pointing the mouse at it and moving it around until it is close to where you want it). There seems to be little logic to how it rotates and the help documentation doesn't even hint at rotation once the extrusion is complete. Unless I've seriously missed something, which is entirely possible

There is an X and Y axis but the center points are never where I would consider the center and so rotation is a mess.

Any help would be greatly appreciated,
Thanks!
