What is the purpose of the Helix feature in SolidWorks?

The Helix feature in SolidWorks is specifically designed for creating helical curves or surfaces, which are essential in applications like springs, threads, and other cylindrical shapes that require a helical path. This feature allows users to define parameters such as pitch, revolution, and direction, enabling the design of complex geometries that closely mimic real-world components like screw threads, coil springs, and other similar structures.

By utilizing the Helix feature, designers can efficiently produce and manipulate 3D shapes that follow a spiral path, making it a crucial tool for any designer working on mechanical parts involving helical forms. This is why the selected answer accurately represents the purpose of the Helix feature.
