I seem to have discovered a bug/fault in how Revit 2017 calculates spaces.
The options to calculate the space/room area by Wall Surface or Wall Centreline no longer work for spaces, only rooms...
Changing these options, both under the Room options and the Space options, works fine for rooms and does nothing for spaces;

Can anyone else replicate this?
Looks like someone forgot to implement this option for Spaces as well as Rooms. It basically screws up a workflow I have used regularly in 2016 to create separation lines from wall centrelines. I guess I will have to reprogram for Rooms instead of Spaces....
