pub fn offset_faces(
part: &mut NamedModel,
namer: &Namer,
faces: &[FaceId],
distance: Scalar,
) -> GeopResult<BuiltBody>Expand description
Copies the faces faces of part — of a solid or of a sheet — into a
sheet distance along their normals (against them for a negative
distance), and returns it: the inner side of the faces shelled (see the
module docs), sharing nothing with them, which stay as they are.
The copy of each face, edge and vertex X is named N(X), with N
the operation.
