Angular Datums

Forgive me if I have already posted this.

For some reason I cannot fathom I can no longer use a datum as a
reference plane to create a new plane at an angle. I can use an edge
or an axis, but not datums.

When I create a new datum, either permanent or on the fly, I use the
"through" menu pick, and then select a datum. When I select
doneSelect, I should see the angle option, but instead ALL the menu
picks are grayed out. If I select done at that point, all I get is a
new datum on top of the one I used for the through plane. The same
thing happens if I try picking angle first.

What gives?

First pick the datum you want the angle based from.
Then hold down Control key and pick inside of the curved surface.
you will then have 45 degree angle, which you can now modify to your spec.

You may swear on mothers and graves that you've created an angular datum by
picking on a datum first, but it's never been possible. Pro/e has always, to this
day, demanded that an edge or preferrably, an axis is picked first (that is what
'thru' refers to) for an angular datum to be a possibility. In fact, create an
axis, say, at the junction of two datums, pick the Create Datum icon while the
axis is still highlighted and you will automatically get an angled datum, with the
nearest datum counterclockwise from zero picked as the angular reference:
axis/edge first, datum second and yeah, don't forget the Ctrl key for 'Add a
feature' to to select the reference datum.
