'architectural graphics'
i stopped reading at page 91 a few pages into the perspective section. i'll get to it later
ching makes a lovely distinction when he writes "Paraline drawings represent either an ariel view looking down on an object or scene or a worm's eye view looking upward. They lack the eye-level view and picturesque quality of linear perspectives. They represent what we know rather than how we see, depicting an objective reality that corresponds more closely to the picture in the mind's eye than to the retinal image of linear perspective".
