Like the plan region, but instead of modifying the view range, you can modify the Visibility/Graphics Overrides.
Sometimes you need to display a portion of the view differently, for example, in a section you want to see the shadows only from outside the building and not from inside, or in a floor plan you want to apply a view filter only to a section of that floor plan, not to all the categories on the entire floor plan.
We usually solve this by creating two views, working with crop regions, and stacking the two views in the same position on the sheet.
It would be much easier to use a tool like Plan Region, where instead of changing the view range, you change the view template or the Visibility/Graphics Overrides.
