Two leaves.
One axis.
The leaf holds the surface. The barrel holds the turn.
Read the object as a set of connected forms. This collection studies their visual relationships.
Barrel
Alternating sections share a center line.
Recess
A small inset changes the light at the surface.
Leaf
An opening breaks up the broad plane.
Follow the
center line.
See the leaf, pin, and opposite leaf move apart around the same axis.
Read the direction


An axis gives
the plane a direction.
Look at the gap beside the barrel. It marks where one plane yields to the other.
Small edges
carry the light.
A bevel, a slot, and an offset each change the silhouette. Look at the outline before reading the face.
