The face to sweep; it must lie on the face of the base that sketchFaceIndex names.
OptionalsketchThe face of the base the profile lies on, counted from 0 as shapes.face.getFaces lists them.
OptionalangleHow far the sides lean from straight, in degrees: a positive angle narrows the feature as it goes away from the sketch face, a negative one widens it.
OptionalextentWhere the feature stops: after length, at the face untilFaceIndex names, or once it has
passed through the whole base.
OptionallengthHow far the feature runs from the sketch face when extent is length, in model units.
OptionaluntilThe face the feature stops at when extent is untilFace: one the profile meets on its way,
such as the underside of an overhang or a void's ceiling.
A base shape, a profile face sketched on one of its faces, a draft angle and how far to sweep the profile for
features.taperedBossandfeatures.taperedPocket, whose sides lean by the angle.
