Extruding Edges
A straight section of a geometry is called an "edge."
Control points are connected by edges. Midpoints are at the center of edges.
Each edge has 2 handles that look like small arrows. There is one handle on each side of the midpoint.
Click and drag a handle on an edge to extrude that edge.
Extrusion is always parallel to the original edge.
