Room boundary polygons

[Kevin.Bell]

Hi,

I've extracted the boundary segments from a room using Room.GetBoundarySegments

This returns a list, which is a list of polygons.

I understand that the first item in the list is the rooms outer perimeter, and then every other item in the list is any 'hole' in the room (caused by walls etc).

Is this a correct assumption?

Thanks.
