In this dialog:
- * **Name** is the name of the mesh object whose elements will be merged.
+ * **Names** contains names of the selected mesh objects whose elements will be merged.
* **Automatic** or **Manual** Mode allows choosing how the elements are processed. In the **Automatic** Mode all elements created on the same nodes will be merged. In **Manual** mode you can adjust groups of coincident elements detected by the program.
+ * **Exclude groups from detection** group allows to ignore the elements which belong to the specified mesh groups. This control is active provided that the mesh includes groups.
+ * **Elements to keep during the merge** group allows to specify elements to keep in the mesh. (By default an element being the first in a group of coincident elements is kept.) It is possible to either select elements in the Viewer or select groups whose elements will be kept.
+
+ * *Selection* button activates selection of elements to keep.
+ * **Elements** button activates selection of elements in the Viewer.
+ * **Groups and sub-meshes** button activates selection of groups and sub-meshes.
+ * **Add** button adds selected elements or groups to the list.
+ * Elements or groups selected in the list can be removed using **Remove** button.

If the **Manual** Mode is selected, additional controls are available:
* **Show double elements IDs** check-box shows/hides identifiers of elements of the selected groups in the 3D viewer.
* **Edit selected group of coincident elements** list allows editing the selected group:
