You can delete a view frame in a view frame group. Or you can delete all view frames within a view frame group by deleting the entire view frame group in Prospector.
The view frame and its associated match line object(s) are removed from the View Frames and Match Lines collections in the Prospector tree, and in the drawing.
Deleting a view frame group also deletes all view frames, match lines, and labels associated with that view frame group.
When you delete a view frame group, any sheets and/or sheet sets that may have already been created by the view frame group are not affected.
The view frame group, and all view frame and match line objects belonging to it, are removed from the View Frame Groups collection on the Prospector tab. The view frames and match lines are automatically removed from the drawing.
