Half Break on View/Section
The Half Break on View/Section command enables you to define a partial or broken view consisting of half of an existing view/sectioned view. In case of sectioned view, half of the view remains in section and half appears as a projected view.
Note: The view is created by altering an existing view. The command resets the Undo/Redo buffer, thus preventing you from undoing any previous operations.
