OK, I know this is really basic, but how the heck do I show a datum plane in a drawing?  I created some planes in a part, with labels, for specific dimensions to be called out in a drawing.  How do I get them to show up so I can add targets and or gtols?  I feel so stupid, but cannot figure this out.  I am bouncing back and forth between SW and ProE I feel like a yo-yo and working all hours :-/
