Function triangulate_with_face_meshes 

pub fn triangulate_with_face_meshes(
    model: &Model,
    shape: &Shape,
    deflection: Deflection,
    kept: Option<&FaceMeshCache>,
    tol: Tolerances,
) -> OgeomResult<(Triangulation, EdgeChords, Vec<FaceMesh>)>

As triangulate_with_chords, with every face’s own mesh beside the welded whole: each face below shape in exploration order, and what triangulate_face_with answers for it with the returned chords. The whole is welded from those same meshes, so they are drawn once. A face kept has drawn before to the same chords is taken from it.
