Interface ThreadOptions

Axial half-width of a flat crest, giving a trapezoidal tooth instead of a pointed V. 0 (default) is a sharp V (ISO/UN). Use a positive value for a power-screw profile: ≈0.18 * pitch ≈ Acme/trapezoidal, up near toothHalfWidth ≈ square thread. Must be < toothHalfWidth.

Radial thread height (crest minus root). Defaults to 0.6 * pitch (≈ISO 60° V).

Total thread length along the axis. Turn count = height / pitch.

Point the tooth toward the axis (for an internal thread to cut from a bore).

Left-handed thread. Defaults to false (right-handed).

Axial distance per full turn.

Core radius (external) or nominal hole radius (internal), at the thread root.

Loft sections per turn — higher is smoother but slower. Defaults to 20.

Axial half-width of the tooth at the root. Defaults to 0.42 * pitch.
