+<p>"Sew border to side" is intended to sew a free border to a
+ mesh surface.</p>
+
+<p>The free border is defined as for "Sewing of free borders".
+ The place where to sew the border is defined by two nodes, between which
+ the border faces are placed, so that the first border node is merged with
+ the first node on the side and the last node of the border is merged with
+ the second specified node on the side.</p>
+
+<p> </p>
+
+<p class="whs4"> </p>
+
+<p>The algorithm is following.</p>
+
+<p>1. Find a sequence of linked nodes on the side such that the found links
+ to be most co-directed with the links of the free border.</p>
+
+<p>2. Sew two sequences of nodes using algorithm of "Sewing of free
+ berders".</p>
+
+<p>For sewing border to side you should define three points on the border
+ and two points on the side. User can select these nodes in 3D viewer or
+ define node by its id.</p>

+<p>Surfaces may be defined by either 2d or 3d elements. The number of given
+ elements of the sides must be the same. The sets of given elements must
+ be topologically equal, i.e. each node of one element set must have a
+ corresponding node in the other element set and corresponding nodes must
+ be equally linked. If there are 3d elements in a set, only their free
+ faces must obey to that rule.</p>
+
+<p>Two corresponding nodes on each side must be specified. They must belong
+ to one element and must be located on an element set boundary.</p>
