5 To generate a \b Filling in the <b>Main Menu</b> select <b>New Entity - > Generation - > Filling</b>
7 To create a curvilinear face from several edges you need to define the
9 \n <b>Input Contours</b> - the list of edges/wires to use for creation
10 of the surface. You can select either several edges/wires or a
11 compound of them. To prepare for the filling, each input wire
12 is converted into a single BSpline curve by concatenating its edges.
13 \n \b Minimum and <b>Maximum Degree</b> of equation of the resulting
14 BSpline or Besier curves describing the surface.
15 \n \b Tolerance for \b 2D and for \b 3D - minimum distance between the
16 created surface and the input contours.
17 \n <b>Number of Iterations</b> - defines the maximum number of iterations. The
18 iterations are repeated until the required tolerance is reached. So, a
19 greater number of iterations allows producing a better surface.
20 \n <b>Method</b> - Kind of method to perform filling operation
22 <li>Default - the standard behaviour.</li>
23 <li>Use edges orientation - the edges orientation is used: if an edge is
24 reversed, the curve from this edge is reversed before being used by the filling
26 <li>Auto-correct edges orientation - curves orientation is changed to
27 minimize the sum of distances between ends points of edges.</li>
30 <b>Approximation</b> - if checked, BSpline curves are generated in
31 the process of surface construction (using
32 GeomAPI_PointsToBSplineSurface functionality). By default the surface
33 is created using Besier curves. The usage of <b>Approximation</b>
34 slows the algorithm, but allows building the surface for complex cases.
36 \n The \b Result of the operation will be a GEOM_Object (face).

46 \note This dialog supports navigation through the selectable objects (in OCC 3D viewer only):
47 - Scroll mouse wheel with pressed \em Ctrl key or press \em "S", \em "P" keys when input focus is
48 in the viewer to navigate between selectable objects.
49 - Press left mouse button to select an appropriate object to the dialog box.
51 For more details, please refer to the \em "Functionality common for OCC and VTK viewers" chapter
52 of the GUI module's documentation.
