Rib

Extends BooleanOperation

Inherited from BooleanOperation

add()

add(): this

Additive boolean operation — fuses the result with all intersecting scene objects. Use .scope() to target specific objects.

---

'new'()

'new'(): this

No boolean operation — keeps the result as a standalone shape, separate from all other scene objects.

---

remove()

remove(): this

Subtractive boolean operation — cuts the result from all intersecting scene objects. Use .scope() to target specific objects.

---

scope()

scope(...objects: SceneObject[]): this

Narrows the boolean operation scope to specific target objects. Must be chained after .add() or .remove().

Parameter	Type	Description
...objects	SceneObject[]	The target objects to operate on. (optional)

Inherited from SceneObject

name()

name(value: string): this

Sets a custom display name for this object, overriding the default type-based name.

Parameter	Type	Description
value	string	The display name to assign.

Methods

startFaces()

startFaces(...args: (number | FaceFilterBuilder)[]): ISelection

Selects faces at the start (base) of the rib — the profile face at the sketch plane.

Returns: ISelection

Parameter	Type	Description
...args	(number | FaceFilterBuilder)[]	Numeric indices or FaceFilterBuilder instances to filter the selection. (optional)

---

endFaces()

endFaces(...args: (number | FaceFilterBuilder)[]): ISelection

Selects faces at the end (top) of the rib — where the rib meets the boundary.

Returns: ISelection

Parameter	Type	Description
...args	(number | FaceFilterBuilder)[]	Numeric indices or FaceFilterBuilder instances to filter the selection. (optional)

---

sideFaces()

sideFaces(...args: (number | FaceFilterBuilder)[]): ISelection

Selects the lateral wall faces of the rib.

Returns: ISelection

Parameter	Type	Description
...args	(number | FaceFilterBuilder)[]	Numeric indices or FaceFilterBuilder instances to filter the selection. (optional)

---

capFaces()

capFaces(...args: (number | FaceFilterBuilder)[]): ISelection

Selects the small cap faces at the spine endpoints.

Returns: ISelection

Parameter	Type	Description
...args	(number | FaceFilterBuilder)[]	Numeric indices or FaceFilterBuilder instances to filter the selection. (optional)

---

startEdges()

startEdges(...args: (number | EdgeFilterBuilder)[]): ISelection

Selects edges on the start faces.

Returns: ISelection

Parameter	Type	Description
...args	(number | EdgeFilterBuilder)[]	Numeric indices or EdgeFilterBuilder instances to filter the selection. (optional)

---

endEdges()

endEdges(...args: (number | EdgeFilterBuilder)[]): ISelection

Selects edges on the end faces.

Returns: ISelection

Parameter	Type	Description
...args	(number | EdgeFilterBuilder)[]	Numeric indices or EdgeFilterBuilder instances to filter the selection. (optional)

---

sideEdges()

sideEdges(...args: (number | EdgeFilterBuilder)[]): ISelection

Selects edges on the side faces, excluding edges shared with start/end faces.

Returns: ISelection

Parameter	Type	Description
...args	(number | EdgeFilterBuilder)[]	Numeric indices or EdgeFilterBuilder instances to filter the selection. (optional)

---

capEdges()

capEdges(...args: (number | EdgeFilterBuilder)[]): ISelection

Selects edges on the cap faces.

Returns: ISelection

Parameter	Type	Description
...args	(number | EdgeFilterBuilder)[]	Numeric indices or EdgeFilterBuilder instances to filter the selection. (optional)

---

draft()

draft(value: NumberParam | [NumberParam, NumberParam]): this

Applies a draft (taper) angle to the rib walls.

Parameter	Type	Description
value	NumberParam | [NumberParam, NumberParam]	A single angle for uniform draft, or a [start, end] tuple for asymmetric draft.

---

parallel()

parallel(): this

Switches the extrusion direction to parallel to the sketch plane (perpendicular to the spine within the plane) instead of normal to it.

---

extend()

extend(): this

Extends the rib's side faces at the spine endpoints outward to blend with the target solids' walls.
