Maybe I am missing something.

If you have an object that is positioned at <0,0,0> and is rotated 45 degrees
on the Y axis, then translate it 1 unit on the X axis, won't it be located at
<1,0,0>???

What I was wanting to do is translate that same object (with it's rotated
axis), 1 unit on it's own X axis.

The approximate coordinates would become < 0.71, 0,  0.71> instead of <1,0,0>
