Helix and Spiral You can create a helix or spiral curve in a part. The curve can be used as a path or guide curve for a swept feature, or a guide curve for a lofted feature. Example - Threads on a Bottle The helix and the sweep profile are on the neck of the bottle. A boss-sweep feature (shown in blue) creates the threads on the neck of the bottle. Example - Spiral Spring Spiral spring Spiral spring in the internal mechanism of a clock Example - Worm Gear Variable pitch helix A cut-sweep feature creates the worm gear.
