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-)​

    Thank you so much...I corrected almost everything, my problem was that I gave the presumed position of these holes at an angle, calculated it and gave it the correct one. I have a bigger problem now, every time I measure the same part of DATUM B it turns in a different direction. The diameter of the piece is approximately 33 in, the height is approximately 5 in. Datum B is a cylinder with a depth of about .300, additionally, the holes at an angle are drilled close to this datum, and the part is made of aluminum.
    I know I have 36 holes, but they asked me to measure 4, which are opposite on both sides.
    Really need help. How to stabilize DATUM B.
    I created 6 circles every .050 and then concentrated them into a cylinder (the circles were ok, but the cylinder was not).​
