-\n <b>Number of
-Iterations</b> - defines the maximum number of iterations. The iterations are repeated until the required tolerance is reached. So, a greater number of iterations allows producing a better surface.
-\n <b>Approximation</b> - if checked, BSpline curves are generated in the process of surface construction (using GeomAPI_PointsToBSplineSurface functionality). By default the surface is created using Besier curves. The usage of <b>Approximation</b> makes the algorithm work slower, but allows building the
-surface for rather complex cases.

+\n <b>Method</b> - Kind of method to perform filling operation

+<ol>
+<li>Default - the standard behaviour.</li>
+<li>Use edges orientation - the edges orientation is used: if an edge is
+reversed, the curve from this edge is reversed before being used by the filling
+algorithm.</li>
+<li>Auto-correct edges orientation - curves orientation is changed to
+minimize the sum of distances between ends points of edges.</li>
