I see an number of posts stating the R7.0 is to be used to create the high point for datum C this is incorrect as the R7 cannot produce the high point..
Datum C is the tangent of the radius 19.8 that is struck from the centre diameter.
I would measure the radius 19.8 then intersect it with a generic line to create the point C Datum
I believe the easiest and quickest option would be to set the alignment as already mentioned then take a single point hit for the 19.8 DIM, the centre of the radius would have to be extremely far off to have any noticeable effect on the dimension.
