- * \brief Create a polyline consisting of 1D mesh elements each lying on a 2D element of
- * the initial mesh. Positions of new nodes are found by cutting the mesh by the
- * plane passing through pairs of points specified by each PolySegment structure.
- * If there are several paths connecting a pair of points, the shortest path is
- * selected by the module. Position of the cutting plane is defined by the two
- * points and an optional vector lying on the plane specified by a PolySegment.
- * By default the vector is defined by Mesh module as following. A middle point
- * of the two given points is computed. The middle point is projected to the mesh.
- * The vector goes from the middle point to the projection point. In case of planar
- * mesh, the vector is normal to the mesh.
- * \param [inout] segments - PolySegment's defining positions of cutting planes.
- * Return the used vector and position of the middle point.
- * \param [in] group - an optional group where created mesh segments will
- * be added.
