Highest point /Theoretical datum plane from radius

Hi, how would i construct a datum/alignment from the highest point on a radius
And how would i get the right orientation for the dimension

Posting pic of datum and the callout/ boxed dimension

  • To Jefman's point, there isn't a connection shown between Datums -B- and -C- orientation to each other or -C- to the part. And the FCF callout is single segment, which means those measurements are independent of each other. The top half would be spatial and origin on -A-, rotation and origin on -B-, and the bore would be allowed to best fit along the -B- axis/direction. The second callout would be the same principle as the top, only using -C-. The problem I see is what is the orientation of -C- to the rest of the part? There's no angle shown and unless there's a flat section on the -C- surface, how do you know what the angle is to rotate/evaluate to?
