-\n To create a curving face using several edges you need to define the
-<b>Edges Compound</b>, \b Minimum and <b>Maximum Degree</b>, \b
-Tolerance for \b 2D and for \b 3D , the <b>Number of Iterations</b>
-and <b>Approximation</b>.
+To create a curvilinear face from several edges you need to define the
+following parameters:
+\n <b>Input Compound</b> - the list of edges/wires used for creation
+of the surface. To prepare for the filling each wire of the compound
+is converted to an edge created on a BSpline curve built using curves
+from all edges of the wire.
+\n \b Minimum and <b>Maximum Degree</b> of equation of the resulting
+BSpline or Besier curves describing the surface;
+\n \b Tolerance for \b 2D and for \b 3D - minimum distance between the
+created surface and the reference edge;
+\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>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>
+</ol>
+
+\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>
+slows the algorithm, but allows building the surface for complex cases.
+
\n The \b Result of the operation will be a GEOM_Object (face).
