| `U or V Span` | Choice     | The direction you want to obtain the span of                                                                                                                                      |
| `Divisions`   | Scalar     | The number of divisions will determine how many cells are created in the U or V direction. If you have a part with a lot of curvature, we recommend a higher number of divisions. |
