Positive Extrusion

Extrusion in modelling is the act of taking a 2D plane, forming a shape on that plane, and then pushing out a solid object in that shape as a cylinder from that plane.

Positive extrusion adds a pillar of solid material to the model in the form of the cylinder created. It can be straight out from the plane, or at an angle. However, it is always in a straight line, and always the exact cross section of the shape on the 2D plane.
