| `Lattice`        | lattice\_body    | Lattice on which filtering is to be done by length in a containment                                             |
| `Condition`      | comparison\_enum | Logical arguments used with the filter criteria, Length.                                                        |
| `Length`         | Scalar           | The filter criteria, beam length from the Lattice.                                                              |
| `Beam thickness` | Scalar Field     | Thickness of the Lattice Beams                                                                                  |
| `Containment`    | Implicit Body    | Containment region for the filtering                                                                            |
| `Choice`         | Choice           | Use Refined Bounding Box option only if the Final Lattice is incorrectly trimmed and has undesired rounded ends |
| `Tolerance`      | Scalar           | Tolerance for the Refined Bounding Box                                                                          |
