-\page reorient_faces_page Reorient faces by vector
+\page reorient_faces_page Orient faces
 
-\n This operation allows changing orientation of a set of neighboring
-faces. The desired orientation is defined by a vector. Since the direction
-of face normals in the set can be even opposite, it is necessary to
-specify a control face whose normal will be compared with the vector. This
-face can be either specified explicitly or found by proximity to
-a given point.
+\n This operation allows fixing the orientation of a set of faces in
+the following ways:
+<ul>
+<li>The required orientation of a set of neighboring faces can be defined
+  by a vector giving the direction of a normal to a certain face. <br>
+  Since the direction of face normals in the set can be even opposite,
+  it is necessary to specify a \a control face, the normal to which
+  will be compared with the vector. This face can be either:
+  <ul>
+    <li>found by proximity to a given point, or</li> 
+    <li>specified explicitly.</li> 
+  </ul>
+</li>
+<li>Alternatively, the faces can be oriented relatively to the adjacent volumes.</li>
+</ul>
 
-Orientation of a face is changed by reverting the order of its nodes.

+<li>To reorient by direction of the face normal:
+    <ul>
+    <li>Specify the coordinates of the \b Point by which the control face

+      node in the 3D Viewer or selecting a vertex in the Object
+      Browser.</li>

-<li>Select the \b Object (mesh, sub-mesh or a group of faces) containing faces to reorient in the Object Browser or in the 3D Viewer.</li>
-<li>Specify the coordinates of the \b Point by which the control face
