expose()

Publishes a named piece of the part's geometry — the part's geometry interface, the outbound counterpart of param() (values in) and connector() (mate frames out). Declared inside a part(...) block, the exposure registers on the part and other parts consume the SOURCE through def.features.<name>:

export const p1 = part('Part1', () => {
  const s = sketch('xz', () => { ... }).reusable();
  expose('profile', s);
});

// consumer part:
extrude(15, p1.features.profile);

Accepts any scene object — a sketch, a face/edge selection, a plane, an axis, or a feature. Raw values are not allowed: an exposure must be tied to real geometry so it re-derives correctly on every render.

Returns: SceneObject

expose(name: string, source: SceneObject): SceneObject

Publishes a named piece of the part's geometry — the part's geometry interface, the outbound counterpart of param() (values in) and connector() (mate frames out). Declared inside a part(...) block, the exposure registers on the part and other parts consume the SOURCE through def.features.<name>:

export const p1 = part('Part1', () => {
  const s = sketch('xz', () => { ... }).reusable();
  expose('profile', s);
});

// consumer part:
extrude(15, p1.features.profile);

Accepts any scene object — a sketch, a face/edge selection, a plane, an axis, or a feature. Raw values are not allowed: an exposure must be tied to real geometry so it re-derives correctly on every render.

Parameter	Type	Description
name	string	Identifier the exposure is registered under.
source	SceneObject	The scene object published under def.features.<name>.
