GEOTOL help

browningdmis
management had me run a test. I taped a 2,4,6 block to the table. took the top plane, x+ and y- and created my alignment. I then called them datum a top b x and c y. I measured 2 holes on each side and did a position in geotol. I used the same measured data in legacy and got a .010 difference. How can this be?

What management is saying is the position formula. 2 x (dx^2 + dy^2)^1/2 when you figure it manually using the measured values matches legacy perfectly but it is not matching in GEOTOL.

I understand this is rough and dirty test but I can not explain why parts we measure good with second methods and legacy are good. GEOTOL (which our customer uses and requires) is failing the part. I have asked Hexagon this question and keep being told that GEOTOL is correct to the standard. Which is great but the standard use the 2 x (dx^2 + dy^2)^1/2 formula and is passing this but failing in GEOTOL.

I am not bashing PCD Hexagon or anything but I can not explain it to management.

What am I missing??​
