Helix

The Helix command in Rhino creates helical curves with several customization options. Key command-line features include:

• Vertical: Creates a helix with an axis perpendicular to the construction plane.

• AroundCurve: Draws a helix around a selected curve.

• Diameter/Radius: Toggle between radius and diameter input.

• Turns: Defines the number of turns; pitch adjusts automatically.

• Pitch: Defines the distance between turns; number of turns adjusts automatically.

• ReverseTwist: Reverses the direction of the helix twist.

These options are useful for designing components such as coiled jewelry, springs, or threaded elements.
