E - Scaling

The Scale parameter allows the geometry to be scaled while being revolved or extruded. All scaling is done with respect to the centroid of the geometry.

Some examples of scaling:

The examples above all use Linear Interpolation for the scaling. Some examples that involve other Interpolations while extruding:

If zero is entered for the Scale parameter, then the geometry will degenerate to a point:
