Endpoint

This is represented by a green circle at the endpoint of any Edge.

Midpoint

This is represented by a light blue (Cyan) circle at the midpoint of any Edge. This point is exactly halfway between the two endpoints of the edge.

Center Point

This is represented by a dark blue circle at the center point of a Circle, Arc, or regular Polygon. This point may not appear when hovering around the center of an object. The Edge of the object should be hovered over first to show the center point and then...
