The primitive surfaceSpiral generates a coplanar set of surfaces that turns from the center to the end point, specified by the width, the radius and the number of turns. Some configurations of these parameters may generate invalid spirals, so the command will return an error with some suggestions for the parameters review.

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