I think I understand your desire to have a spot-on, exact copy of a Strat.
But, being practical, even if you were to get a CAD file and have a template laser-cut, just the sanding of the body after it's cut is going to put it off from the original some fraction of a millimeter anyway. It's just a question of how close is good enough, because you're not going to get something perfect no matter what you do. (And in fact, factory Strats are going to vary from each other to some small degree anyway.)
