String

Surface and Opening elements get an Name element assigned according to the below described schema:

(Orientation)(Space#)[(Other space#)](Exposure)(Type)-(sequence number)[Opening Type+#]

Sample: N-101-102-E-W-O-77

N = Orientation [N/NE/E/SE/S/SW/W/NW/N/T/B/X] (every surface within the sector of 22.5 degrees from the north vector gets the letter N etc) (horizontal surfaces facing upwards get the letter T for top, downwards B for bottom) (shading surfaces get the letter X for differentiation).
101 = Space number.
102 = Other space number.
E = Exposure - exterior/interior/underground [E/I/U].
W = Type [W/C/R/F] (Wall, Roof, Ceiling, Floor, Shade) (every surface type has it's letter W-Wall R-Roof C-Ceiling F-Floor S-Shade).
O = Opening Type [W/D/O] (Window, Door, Opening) (every opening type has it's letter W-Window D-Door O-Opening).
77 = sequence number.
