Yes Keith, you are reading this correctly, it's oh how shall we say...all wrong in other words. Datum -A- is a diameter??? Are they still requiring parallel of -C- to the AB center line? I'll review this and reply later tonight, in the mean time review the "datum designation" reply from Duane Wade 8/17 also in the GD&T conference.
