It's a target point on the 15° lollipop stick. I couldn't find B.

-A- is the flat plane at the bottom of the part, -B- is a 22.5 diameter through -A-, -C- is a single point located 105.88 up from -A- and
110 away from centerline of -B- on the side of the part. Since everything is called back to these datums I would use them as a base alignment.

Shabu, you will probably need to use the special tab found in the base alignment or any other alignment and rotate to the distances of 110 and 105.88 to rotate the alignment back to how it is showing within the print. It might be easier to setup a simple base alignment for the CMM to find the part, and create a separate alignment for these features. Also, because only one hole has basics as shown (hole with the 138.5 and 113.52) the other holes will not match the basics called out on the print. Hopefully you are using a solid model that has been verified so you can trust the coordinates it gives you.
