Area Settings>Advanced Settings>Exterior Area Expand

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.
