need a straight answer on how a real length of an object is projected into the perspective on paper? since the perspective have lines extending to infinity through vanishing points, and these lines are used to define an object's form, but the problem is that i dont know how does the real length is drawn into it, so it is now a matter of calculating
like this picture i guess how the orthogonal drawing is placed in tilted manner so is it a must for it to be tilted than directly using a ratio of the lines?
what is the calculations or methods to this?
