Settle the large planes before any detail
Held that the big planes of which the small forms are only a part must be understood first, so the eye finds the front, the side, and the top of a mass before it touches an eye, a lip, or a knuckle.
Why it matters · Most beginners draw the features and then try to hang a head around them, and it never sits in space. Vanderpoel reversed the order. Get the large planes right and the detail later drops onto a form that already turns in three dimensions. It is the same logic Bridgman taught a generation later at the Art Students League.

Picture the head as a cube with rounded corners
Taught the student to see the head not as a soft oval but as a block, "a cube with all its corners and edges rounded," so its six planes could be felt mentally even when only a few were visible from a given view.
Why it matters · A cube has a clear front, sides, top, and bottom, and each one catches light differently. Thinking of the head as a rounded cube gives you the planes to model against, which is why a drawn head reads as solid instead of as a flat mask with features painted on.

Light the figure to separate the planes
Lit the model deliberately so the strong light and shade marked where the breadth of a form, its front or back, broke away from its thickness, then drew that separation as the structure of the figure.
Why it matters · Light is not decoration on the form, it is the thing that tells you where one plane ends and the next begins. His own charcoal studies are titled for exactly this, separating front from side through strong light and shade. Set your light to reveal the turn of the planes and the shadow does your drawing for you.

Draw in two periods, place the part then turn it into form
Split the act of drawing into two stages of mind: first the search for the relative place each part occupies in the whole, then the work of turning that placed part into its actual, modelled form.
Why it matters · Trying to place a form and finish it in the same breath is why drawings go tight and wrong. Vanderpoel kept the two jobs apart. Locate everything in relation to everything else first, then and only then model it. The discipline is refusing to render a part before its place is true.
John H. Vanderpoel, The Human Figure (the two periods of drawing), 1907
Hold the standard, even over a student's feelings
Was gentle in person but exacting at the easel, reported to have told a student labouring over a hopeless sheet, "You're only dirtying your paper. Start another drawing," and to have kept after a pupil whose figures leaned left until she got glasses for her astigmatism.
Why it matters · A teacher who praises everything teaches nothing. The kindness and the hard standard were the same act for him. The lesson for a working painter is to be that honest with your own sheet: when a drawing is built on a wrong placement, the fix is a fresh start, not more rendering.

Turn the method into a system anyone could carry
Wrote his lectures down as The Human Figure in 1907, illustrated with about 430 of his own charcoal and pencil drawings, so the plane-by-plane method left the Chicago classroom and reached students who never met him.
Why it matters · A method kept in one studio dies with the teacher. By setting his down as a book, Vanderpoel made it transmissible: the Chicago Artists essay reports it ran through ten editions and sold 45,000 copies by 1921, and it is still in print. The move is to make your own working knowledge explicit enough that it can be handed on.
