Thanks for the help I finally got it to work. I am not sure where the create the datum on the fly command is. MY problem was I was not holding the control key when trying to reference the datum to offset from after I had selected the center axis to revolve through, hence I would get no angular dimension. Is there an easy way to group things rather that going trough Edit/Feature operations and using the group command from the menu.
