You need to determine if your requirement is to drive the diameter as a function of the 4" center, or if the 4" dim is allowed to float in a range. This will affect the structure of the part. Also, is the 4" a chordal dim, or an arc length?

I still havent got this figured out. this is going to be a clearnance hole and the 4.00 dimension can be rounded up or down from the 4.0 inches so the spacing will be equal

what is the best way to do this?

Thanks in advance R
