The primitive spiral generates a coplanar curve that turns from the center to the end point, specified by the radius and the number of turns. The first point of the curve is at the center and the last point is at the radius distance.

By default, the generated spiral is generated in counter-clockwise direction. To generate spirals in clockwise direction, the parameter “-rightTurned” must be included.
