For solvecraft-params' Split Face feature: - Sketch tools are chains of Seg2. A single line splits by its plane and a single arc by its cylinder, exactly (a circular edge on a planar face); longer chains and splines follow the curve. - split_faces_with_map gives the source face of each face of the result. - A listed face the tool misses is an error naming it (split_any keeps the lenient form for Trim).
