 \page convert_to_from_quadratic_mesh_page Convert to/from Quadratic Mesh
 
-\n This functionality allows you to transtorm standard meshes to
-quadratic and vice versa. See \ref adding_quadratic_elements_page "Adding quadratic elements" 
-for more information about quadratic meshes.
+\n This functionality allows transforming linear meshes (or
+sub-meshes) to quadratic and vice versa.
+Note that conversion of a sub-mesh most probably will produce a
+non-conformal mesh. Elements on the boundary between quadratic and
+linear sub-meshes become (or remain) quadratic.
+
+See \ref adding_quadratic_elements_page for more information about
+quadratic meshes.
 
 <em>To produce a conversion:</em>
 <ol>
-<li>From the Modification menu choose the Convert to/from Quadratic
-Mesh item, or click <em>"Convert to/from quadratic"</em> button in the

+<li>From the Modification menu or from the contextual menu in the
+  Object Browser choose <b> Convert to/from Quadratic Mesh</b> item,
+  or click <em>"Convert to/from quadratic"</em> button in the
