VIII LINE DRAWING: PRACTICAL

Seeing that the first condition of your drawing is that it has to be made on a flat surface, no matter whether it is to be in line or mass you intend to draw, it is obvious that appearances must be reduced to terms of a flat surface before they can be expressed on paper. And this is the first difficulty that confronts the student in attempting to draw a solid object. He has so acquired the habit of perceiving the solidity of things, as was explained in an earlier chapter, that no little difficulty will be experienced in accurately1 seeing them as a flat picture.
Observing Solids as a Flat copy.
As it is only from one point of view that things can be drawn2, and as we have two eyes, therefore two points of view, the closing of one eye will be helpful at first.
The simplest and most mechanical way of observing things as a flat subject is to have a piece of cardboard with a rectangular hole cut out of the middle, and also pieces of cotton threaded through it in such a manner that they make a pattern of squares across the opening, as in the accompanying sketch3. To make such a frame, get a piece of stiff cardboard, about 12 inches by 9 inches, and cut a rectangular hole in the centre, 7 inches by 5 inches, as in Diagram III. Now mark off the inches on 85all sides of the opening, and taking some black thread, pass it through the point A with a needle (fixing the end at this point with sealing-wax), and across the opening to the corresponding point on the opposite side. Take it along to the next point, as shown by the dotted line, and pass it through and across the opening again, and so on, until B is reached, when the thread should be held by some sealing-wax quite taut4 everywhere. Do the same for the other side. This frame should be held between the eye and the object to be drawn 86(one eye being closed) in a perfectly5 vertical6 position, and with the rectangular sides of the opening vertical and horizontal. The object can then be observed as a flat copy. The trellis of cotton will greatly help the student in seeing the subject to be drawn in two dimensions, and this is the first technical difficulty the young draughtsman has to overcome. It is useful also in training the eye to see the proportions of different parts one to another, the squares of equal size giving one a unit of measurement by which all parts can be scaled.
