“In an architectural drawing, the rich reality of the building being drawn is always fighting a losing battle with the limitations of the drawing itself. There are two possible consequences of that defeat. One is that the drawing ends up a very poor substitute for the actual thing. The other, and this always happens in a good drawing, is that some aspect of the design deemed important for a particular purpose can, by the exclusion of many other aspects, be more vividly rendered, possibly even more vividly than in the actual building.” (Allen&Oliver, 1981, p.14)
