+<h2>Making 0D elements on Element Nodes</h2>
+
+There is another way to create 0D elements. It is possible to create
+0D elements on all nodes of the selected mesh, sub-mesh, or a group of elements or nodes.

+ <li><b> Set Filter </b> button allows selecting elements or nodes
+by filtering mesh elements or nodes with different criteria
+(see \ref filtering_elements "Filter usage").</li>
