Shell and thicken¶

Shell hollows a body, and Thicken gives a face a wall of its own.

For Shell, click the faces that should open, then drag or type the wall thickness. A mug is a cylinder with its top shelled to a few millimetres.

For Thicken, click the face and set the thickness, and press S to grow the wall on both sides. Its Operation row chooses between New body and Join.
