if there are other features for that snap ring groove (im assuming) then you would include those features also to associate it for datum a. (construct it as a cylinder)

It's for an o ring. There is actually 4 of them down the part. They only want the axis of the od cylinder as the datum. The part is like 14 inches long.
They want a od cylinder and a construction line though the axis of only that cylinder. They do not want the axis of the part just of thay od cylinder.
