Scale drawing gets promotion (9)
I believe the answer is:
elevation
I believe this is a double definition.
'scale drawing' is the first definition.
(I've seen this before)
'promotion' is the second definition.
(I've seen this before)
'gets' is the link.
(Other definitions for elevation that I've seen before include "Diagram" , "Height above a given level" , "scale drawing" , "plan" , "Drawing of the external face of a building" .)
