+existing group and some other faces selected in the viewer:
+<ul>
+<li> select the "Face" type of entities and input the name of the new group.</li>
+<li> checks "Group" checkbox in "Select From" group.</li>
+<li> select the existing group in the object browser or in the viewer.</li>
+<li> click "Add" in "Content" group. "Id Elements" list will be filled
+with IDs of faces belonging to the exising group.</li>
+<li> select other faces in the viewer.</li>
+<li> click "Apply" button to create the new group.</li>
+</ul>
