  • Within Pro/Engineer, the Helical feature is created by sweeping a section along a helical trajectory.
  • The trajectory is defined by a surface of revolution (An open section curve that defines the outer profile of the helical shape), and a "pitch" parameter (the distance between the center of one revolution and the next).
  • The Axis of revolution is a straight Centerline and therefore cannot be curved
