Clicking this button starts one of the following processes if there are any visible meshes.

Remove Stitching Faces If You Want

If these meshes contain stitching faces, a dialog window is pop up to ask if you want to remove them.

Merge Points

A dialog window is pop up to ask for the "Point Merging Radius (m)" and "Min. Vertex to Line Distance (m)" parameters, and the "Merge Points To One" is automatically turned on. Then all the points are merged these parameters.
