+\note All dialogs for quadratic element adding to the mesh
+provide the possibility to automatically add an element
+to the specified group or to create the group anew using
+<b>Add to group</b> box, that allows choosing an existing group for
+the created node or element or giving the name to a new group. By
+default, the <b>Add to group</b> check box is switched off. If the user
+swiches this check box on, the combo box listing all currently
+existing groups of the corresponding type becomes available. By
+default, no group is selected. In this case, when the user presses
+<b>Apply</b> or <b>Apply & Close</b> button, the warning message box
+informs the user about the necessity to input a new group name. The
+combo box lists both \ref standalone_group "standalone groups"
+and \ref group_on_geom "groups on geometry". If the user chooses a
+group on geometry, he is warned and proposed to
+\ref convert_to_standalone "convert this group to standalone".
+If the user rejects conversion operation, it is cancelled and
+a new quadratic element is not created.

To create any <b>Quadratic Element</b> specify the nodes which will form your
triangle by selecting them in the 3D viewer with pressed Shift
table. To define the middle nodes for each edge double-click on the
respective field and input the number of the node. All edges and the
object formed by them will be displayed in the Object browser. When
-all edges are defined you will be able to click \b OK or \b Apply button to
