The first item is I erased Set Datum B and changed my mind and wanted to show it. Creo tells me there are no "Model Datums" or "Gtols" to display. So, I figured I would work around and create a new view, move dim's and re-establish the detail view. Dim's can be moved, but it does not appear the detail view "Reference Point" cannot be redefined on the other view. Originally I figured I would use Datum B from the newly established view and then it dawned on me when I delete the view, the datum will go with it. Any ideas on how to get Datum B to re-display?
Use the drawing tree.
In the annotation tab, select the view, expand the view in the drawing tree, expand datums in the drawing tree. You should see your erased datum there and be able to unerase it.
