The only drag about having to use this icon is that it also shows every screw hole annotation on your part or assembly. That SUCKS ! Only in Pro/E WF 5 are you required to do this. Prior to WF 5, all you needed to do was choose the datum plane and select your references and it would show right away - no need to show screw holes as well. This is yet another WF 5 step backwards, along with the entire drawing mode "enhancement".
