part()

Declares a reusable part: a named body of part-design statements with an optional param() interface. Returns a LAZY definition — geometry builds per variant when the definition is inserted (insert(def, { Length: 380 })) or when the defining file renders standalone:

export const bushing = part('Bushing', () => {
  const bore = param('Bore', 10, 'number', { min: 4 });
  const s = sketch("xy", () => { circle([0, 0], 30); circle([0, 0], bore); });
  const e = extrude(20);
  connector('top', e.endFaces());
  expose('profile', s);
});

Equal override values share one template per scene (repeat inserts are cheap); geometry published with expose('name', source) is read back as def.features.<name> (the callback's return value is ignored).

Every part is exported from the top level of its file, and its name is unique within the file. A part() nothing exports (or exports only as default), one written inside another part's or assembly's body, and a second part of a name the file already used are build errors on that part(): the part does not build, and its row says why.

Returns: PartDefinition
