What does Exterior Area Expand do? It is 0ft to 3.3 ft.
It literally makes your entire area larger by that many feet from the current mapped area boundary. I wouldn’t recommend using this unless you mapped the entire area with X amount of FT of safety and it’s too small. Even then, I would recommend using the map area edit feature instead.
It is a little bit confusing, because it is possible to use “Boundary Set Back” and “Exterior Area Expand” at the same time.
It’s confusing, because I guess they are doing the exact opposite and cancel each other out.
