+  <li> if the mesh is computed on a geometry, then "Clear Mesh Data" removes
+    all elements and nodes.</li>
+  <li> if the mesh is not based on a geometry (imported, compound, created from
+    scratch etc.), then "Clear Mesh Data" removes only the elements and
+    nodes computed by algorithms. If no such elements or nodes have been created, can remove nothing.</li></ul>
