Displaying Annotation Views
You can display annotation views with several methods. Right-click an
annotation view and select:
Activate.
Displays the annotations contained in the selected view. An arrow 
indicates when an annotation view is active. You can also
double-click an annotation view to activate it.
Orient (available
when an annotation view is already activated). Displays the annotation
view normal to its plane.
Activate and
Reorient. Displays the annotations contained in the selected view
and displays the annotation view normal to its plane.
Show (available
when an annotation view is not activated). Displays the annotations contained
in the selected view, but does not activate the view. Show is helpful
when you want to insert an annotation in one view, but you need to see
annotations from another view. A view whose annotations are visible, but
not activated, has a blue icon 
.
Hide (available
when an annotation view is not activated). Hides the display of annotations
in the selected view.
If you insert
a 3D annotation in a sheet metal part, a Flat
pattern annotation view is automatically created in the Annotations
folder. When you select the Flat
pattern annotation view, the Flatten
tool is unavailable.
