An arcEdge between two points on a circle. The arc is defined either by a third point that the arc passes through, or by the angle of the sector and the axis of the circle.
If the angle-axis specification is used, the axis may not be not perpendicular to the line connecting the end points. In that case, the axis is considered to be that of a cylinder, and the arc represents a portion of a helix on the surface of that cylinder.
