Re: how to decide outside walls
There's no method in the program to detect outside walls.
Maybe you could reuse wallsAreaCache handled in PlanController to get its exterior path(s) using getAreaPoints in Object3DBranch. The exterior walls should be the ones that intersect with this exterior path, but that won't work if an interior wall touches the border of an exterior wall.
