| Option                  | Description                                                                                                                                                               |
| ----------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Boundary Threshold      | Distance Threshold at which the boundary vertices are coincident                                                                                                          |
| Use Edge Closest Point  | Whether the correspondent vertices are glued to the closest point on edges.                                                                                               |
| Vertex Threshold        | The Maximum Threshold between the original position and the welded position                                                                                               |
| Merge Vertex Tolerance  | Edges are coincident if both pairs of endpoint vertices are closer than this distance                                                                                     |
| Merge Search Tolerance  | Edges are considered as potentially the same if their midpoints are within this distance. Due to floating-point roundoff this should be larger than MergeVertexTolerance. |
| Merge Only Unique Pairs | Only merge unambiguous pairs that have unique duplicate-edge matches                                                                                                      |
