I think I have posted this in old Wishlist but it did not make it here, so here I am again.
Often there is a situation in which we need to create a zone/space outside of the object such as balcony.
If I want to stick to automatically place zone based on boundaries or reference lines, I need to create a Line/Polyline defining the space. But in case of the balcony, there is usually a Railing. Why not to use this Railing as a zone boundary?
