I need help with measuring TP

Malgorzata
Good morning All,
I have a problem with TP. The position of the cylinders on the cone is at an angle. I need to understand why TP is out of tolerance if the diameter and position of these cylinders are correct.
Every tip is valuable.

-A- -> TOP PLN ( Z+ )
-B- ->ID CYL in center ( Z+ )
-C- -> cylinder on the side ( Y-)​

  • measure datum 'A' plane
    measure datum 'B' circle
    measure datum 'C' circle

    create a line between circle 'B' and circle 'C'

    align datum 'A' in Z and datum
    align the created line in 'Y' axis
    datum circle 'B' in X and Y axis

    Do the same thing again in auto, When you do datum 'C' use a sample hit inline with the hole ( ie 12 clock )

    when you measure the angle holes use a sample hit on the angled surface or even better measure the angled hole as a cylinder and measure a line on the angled surface at the center of the hole and intersect the 2 features.

    As the angled holes are 10' apart you should be able to do a paste with pattern.

    Hope this helps.

    There is one problem...

    DATUM A - PLANE - Z
    DATUM B - CYLINDER - facing up - can controls X and Y
    DATUM C - on the side - can controls Z and X
