Extruding along a curve

This video explains how to extrude a circle along a curve and then animate an extrusion. When we ‘extrude’ a 2D shape such as a circle, it means that we will push that shape out. By using a curved line, we can push the shape out so that it follows the line.

Tip: When selecting the circle and CV curve, select the circle first and then hold down Shift key to select the CV curve. Make sure you select the curve last.
