It would be good to include this option. Its very rare that all sides of the space or room will have the same wall type.

The user ends up having to delete or mod most of the walls or even worse not using the tool at all.

With this option, the OBD highlights the segment of the space / shape and allows the user to confirm. if the user confirms then the next segment is hightlighted and so on. Similar to Mstn Create Complex Chain / Shape behaviour.

Spaces and Shapes are increasingly used as starting points for laying out accomodation blocks etc. It would be good to help working up the design as quickly as possible.

Also useful for the later stages, where Shapes and Spaces can be used to add linings.
