GLOSSARY ENTRY (DERIVED FROM QUESTION BELOW)

Italian term or phrase: quadro
Quella parte della geometria che ha per scopo la rappresentazione delle figure spaziali mediante figure di un certo piano detto quadro (o, in casi particolari, mediante figure di una prefissata superficie), in modo che dall'immagine della figura (e, s'intende, dalla conoscenza della legge di rappresentazione) si possa ricostruire la figura spaziale.

This is a definition of descriptive geometry. Wikipedia's entry has not helped me to identify what is meant by quadro here. Any help much appreciated.

projection plane
Explanation:
Also known as plane of projection. Wikipedia cryptically defines it as a type of view in which graphical projections from an object intersect.
In other words, it's the plane on which the lines starting from a centre of projection end up after passing through each vertex
that makes up that object. This means that any technical drawing is by definition a projection plane as it represents a 2D (planar) view
of the object, and that's probably why it's called quadro in Italian. After all, quadro can also be used to indicate a technical drawing or
exercise in Italian drawing classes.
Wikipedia also mentions that a projection plane can be called a picture plane in perspective drawing but, even though this
phrase sounds very similar to quadro, I'm not sure it can be applied to all kinds of axonometry. Here's a further clue:
in Assonometria (IT): "il principio alla base dell'assonometria è la proiezione di un oggetto geometrico su un piano (piano di proiezione o quadro)".

Sorry. I made a mistake and I feel I need to clarify. The plane of projection is actually in between the object we're
trying to represent and the observer.

Oh, it's just I realised the centre of projection, from which the projector lines stem,
is actually behind the observer and not behind the object. But you are right... that
mistake does not affect the translation.

Proiezione parallela
Nelle proiezioni parallele gli elementi di riferimento sono individuati da un centro di proiezione improprio, cioè da una direzione, e da un piano di proiezione, detto piano di quadro o semplicemente quadro. Secondo l'angolo che forma la direzione di tale centro di proiezione rispetto al quadro, le proiezioni parallele possono essere suddivise in due categorie: proiezioni ortogonali e proiezioni oblique.
