QUICK WAY FOR ALIGNING IN WORLD COORDINATE SYSTEM (iterative alignment)

Any more information?

i.e. what's wrong with existing methods; iterative / 3D best fit / 3-2-1 using force alignment in car body?

good morning to all, un even contour surface can use this iterative mothed

Without more detail I'm going to mark this request declined. As noted above there are already some existing tools that preserve the CAD Coordinate system. Idea threads to improve those tools, or even a new alignment method is of course welcome!
