Drawoh/Kenat: Sorry for delay in replying, I took your advice and used the bore as a datum with the tapped holes located from the datum. Thanks for all your help
There are some other separate features that I want to tolerance to the centreline so I was hoping to find a way to show the vertical centreline based on the 45 degree holes as a datum.
Also what is the correct way to show that the hole is located on the diameter and include the tolerance?

Thanks for the quick response.
The feature that defines the vertical centreline are two other holes at 45 degrees as shown in attached sketch, however I am not sure how to use these features to define a datum...
I need some help on a part I am designing. I have a cylindrical part with two ODs, I need a hole to be located on the smaller OD (tolerance of +/-.002") and centred on the vertical centreline of the part (also tol +/-.002). I know that I cannot use a centreline as the datum and am wondering on...
