<p>This link condition is a combination of cyclic rotational and planar symmetry. First, the cyclic
            symmetry is enforced, and afterward the surface is modified to ensure plane symmetry in
            each segment. The plane for each segment cuts the segment into two halves. The following
            parameters are necessary for the definition of the link condition:</p>
<pre class = "codeblock">
<code class = "ph codeph">
CLIENT           = SURF_CYCLIC_PLANE_SYM
CLIENT_DIR       = &lt;X_1&gt;, &lt;X_2&gt;, &lt;X_3&gt;
CS               = name_of_coord_system
TOL              = tolerance_value
ANGLE            = angle in degree
CYCLIC_SYM_START = &lt;X_1&gt;, &lt;X_2&gt;, &lt;X_3&gt;
</code>
</pre>
<p>In comparison to the <code class = "ph codeph">SURF_CYCLIC_SYM</code> case, the <code class = "ph codeph">CYCLIC_SYM_START</code>
                                    point is really important here. As it defines the starting point
                                    of the partitioning process, this point directly influences the
                                    areas that will be made plane symmetric. Its coordinates are
                                    given with reference to the global cartesian coordinate
                                    system.</p>

<p>The figure above shows the differences between the different <code class = "ph codeph">SURF_*_SYM</code> restrictions. 
From left to right this is a) plane symmetry (<code class = "ph codeph">SURF_PLANE_SYM</code>), b) cyclic symmetry (<code class = "ph codeph">SURF_CYCLIC_SYM</code>)
and c) the combination of plane and cyclic symmetry (<code class = "ph codeph">SURF_CYCLIC_PLANE_SYM</code>).</p>
