\n This operation allows changing the orientation of a set faces in the following ways:
<ul>
-<li> The new orientation of a set of neighboring faces can be defined
+<li>The new orientation of a set of neighboring faces can be defined
by a vector. <br> Since the direction of face normals in
the set can be even opposite, it is necessary to specify 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>

The orientation of a face is changed by reverting the order of its nodes.
