Well it seems that all this time I've had it wrong.? Fortunately, I've never discussed this with anyone so it's my secret.? How it came to pass I'm not sure but my X Y&Z has always been to me that X is left right, Y is front to back (milling machine) and Z is vertical.? It seemed to make sense to me so I've adapted this.? Not being a math genius or a CAD operator or working with anyone else equipment? or drawings I don't see any problem.? I have seen the "follow the thumb" rule but that has always been associated with electricity.? Tell me if I should change my thinking. Warren
