Limbs and extremities as simple forms (arms, legs, hands, feet)

Build arms, legs, hands, and feet from simple 3D forms to place, rotate, and bend them in space before adding detail.

What it is

Reduce each limb to basic 3D forms. Upper arms, forearms, thighs, and calves become cylinders or boxy wedges, with joints placed where they bend or twist. Fingers and toes become small boxes or cylinders linked together.

Lay in the pose by showing each form’s direction, foreshortening, and plane changes. Mark the top, side, and front planes of the hand and foot before adding muscles, tendons, or nails.

Interpret limbs from reference as simple forms by identifying the main block and cylinder. When drawing from imagination, build the pose from these parts before refining the anatomical shape.

Why it matters

This structure helps you place elbows, knees, hands, and feet accurately in space. Weak control can make joints bend incorrectly, hands flatten, or feet appear disconnected from the pose. Simple forms also give you a basis for rotating limbs, adjusting angles, and adding anatomical detail.

You can check it when

✓Redraw an arm, leg, hand, or foot from a photo using only boxes and cylinders. The limb and its gesture should remain readable.
✓Turn a drawn limb 90 degrees in your sketchbook, such as from front to side view, using the same simple forms without new reference.
✓Start hands and feet as 3D blocks with defined top, side, and front planes. Check that elbows, knees, wrists, and ankles keep consistent hinge-like bends across drawings.
