I have a question that has been bothering me for a while, I posted a sample of the code. I am measuring the position of 7 cylinders that are pictured in the drawing, (i cannot post the actual drawing forgive the artistry). I align the part to the datum structure, and when I report the locations in the Position Xact measure the holes are varying in distance over the course of the 10" the cylinders run. When I measure the same dimensions with a height stand using my datum C as 0.00" they are all the same distance from the datum. Why am I seeing the error? Datum B and Datum C are not very square to eachother, and datum A about 0.002" perpendicular to both other datums. Is the combination of these errors causing this variation. They vary by about 0.007" in distance and the angle between datum B and C is 90.04°. Thanks For any Help.
