It is important for my students to learn how to break down these complicated skeletal forms into basic geometric shapes to better understand their construction. My ultimate goal is to teach students to draw these complicated forms from memory. Take the skull for example; understanding it’s basic geometry allows us to visualize tumbling this complex form in space and being able to draw it any position from our imagination. To do this, a student needs to appreciate this form’s simplest planes and components. Every edge and/or plane illustrated in this example represents a specific form: the edge you see running horizontally along the side of the face sets up the border between the cheek bone (the zygomatic bone and widest part of the face) and the side plane of the skull. This edge is also an important anatomical land mark that sets up the bottom of the orbital cavities.
