+\note All dialogs for adding quadratic element 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
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".
+combo box lists groups of all the
+\ref grouping_elements_page "three types": both
+\ref standalone_group "standalone groups",
+\ref group_on_filter "groups on filter", and
+\ref group_on_geom "groups on geometry". If the user chooses a
+group on geometry or on filter, he is warned and proposed to
+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
-element by selecting them in the 3D viewer with pressed Shift
-button. Their numbers will appear in the dialog box as <b>Corner Nodes</b>
-(alternatively you can just input numbers in this field without
-selection). The edges formed by the corner nodes will appear in the
-table. To define the middle nodes for each edge, double-click on the
-respective field and input the number of the node (or pick the node in
-the viewer). For bi-quadratic and tri-quadratic elements, your also
-need to specify central nodes.
