When Customer Defaults->Drafting->Flat Pattern View, tab "Callouts", the callout options are ON, Flat pattern callouts are visible in the placed drafting views in the earlier versions of NX.
However in the newer versions of NX, Flat pattern callouts are not visible in the drafting views.
SolutionThose callout options are applicable only for legacy flat pattern callouts.
The callouts in NX2206 are PMIs. This is an enhancement.
So to make them visible in drawing views, you need to follow the same procedure to place PMIs in the drafting views
