Module threads 

Cosmetic threads: threads recorded on a round face rather than modelled — what a drawing, a bill of materials or a fastener check reads, and what the viewer draws as a helix on the face. Held as the part’s target threads, and drawn as the annotations of the step that recorded them (draw_threads).

They are the framework’s, not the hole’s that taps one: a step that repeats features — a pattern, a mirror — copies the threads they carry and draws its copies, knowing no step that records one.

Structs

CosmeticThread

A thread recorded on a round face, straight or tapered, by its specification and where it lies — kept as geometry, so that it says the same whatever later steps do to the face it was put on.

Threads

A part’s cosmetic threads, by name: the value of its target threads, which every step that records one revises.

Functions

draw_threads

Draws the threads the step recorded on the part, as its annotations: what a step that records threads does after.

read_threads

The part’s cosmetic threads as reader reads them: none, before the first step that records one.

threads

The part’s cosmetic threads.
