Grouping reference planes

[cr_gixxer]

correct me if I'm wrong, but I recall being able to include reference planes within a detail group as well as a model group. Now they are only grouping with model groups only.
Am I taking crazy pills or is this something that changed in 2013?

Crazy pills it is ;)
You could actually create the group in previous releases from the annotate tab but it was a Model Group. You can't mix and match without using 'Attached Detail Groups' and RP's are considered model objects.
