➢To create a helical sweep, sweep a section or cross-sectional sketch along a helix or helical trajectory. To define the helix, you define a helix profile, and a helix axis.
➢When the system rotates the helix profile 360° around the helix axis, a surface of revolution is defined. The surface of revolution is not visible, but the concept is depicted in the image.
➢A helical sweep is created. The surface of revolution defines the distance between the origin of the sweep section and the helix axis of revolution. The helix lies upon the surface of revolution.
➢You can adjust the parameters of the helical sweep, such as the pitch which is the distance between coils, and the section orientation. You can use a constant section, or a section that varies as it sweeps along the trajectory.
