\page reorient_faces_page Reorient faces by vector
\page reorient_faces_page Reorient 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 changing orientation of faces two ways.
<ol>
<li> To reorient a set of neighboring faces by defining the desired
orientation 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 whose normal 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> To reorient faces with relation to adjacent volumes. </li>
</ol>
Orientation of a face is changed by reverting the order of its nodes.
<em>To change orientation of faces:</em>
<ol>
<li>In the \b Modification menu select <b>Reorient faces by
vector</b> item or click <em>Reorient faces by
vector</em> button in the toolbar.
<li>In the \b Modification menu select <b>Reorient faces</b>
item or click <em>Reorient faces</em> button in the toolbar.
