Would appreciate any input on how to interpret and how to have PCDMIS interpret the following position callout on the inside sphere per ASME. A is the face of the part, which is fine. But B is the angle of the taper? with MMB?

Which would be the most accurate way for PCDMIS to dimension what's intended:

Autocone and use the cone as the datum -- easiest

Constructed circle intersected at the gage point

Constructed midline between two tangent lines somehow simulating the angle of the cone? MMB how?
