I'm checking over some old parts and making sure the countersink angles are correct.  The parts are derived, and I don't have access to the masters so there's no information in the FeatureManager Tree.  With the measuring tool I can get the large and small diameters as well as the distance between, so I can calculate the angle manually.  But surely there must be an easier way?  I don't understand why I'm having such a difficult time with this...

Thanks for the help.
