Filling Surface with Edges

To generate a Filling in the Main Menu select New Entity - > Generation - > Filling

To create a curvilinear face from several edges you need to define the following parameters:
Input Contours - the list of edges/wires to use for creation of the surface. You can select either several edges/wires or a compound of them. To prepare for the filling, each input wire is converted into a single BSpline curve by concatenating its edges. List of edges/wires must contain more than one edge.
Minimum and Maximum Degree of equation of the resulting BSpline or Besier curves describing the surface.
Tolerance for 2D and for 3D - minimum distance between the created surface and the input contours.
Number of Iterations - 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.
Method - Kind of method to perform filling operation

1. Default - the standard behaviour.
2. 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.
3. Auto-correct edges orientation - curves orientation is changed to minimize the sum of distances between ends points of edges.

Approximation - 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 Approximation slows the algorithm, but allows building the surface for complex cases.

The Result of the operation will be a GEOM_Object (face).

Note

This dialog supports navigation through the selectable objects (in OCC 3D viewer only):

• Scroll mouse wheel with pressed Ctrl key or press "S", "P" keys when input focus is in the viewer to navigate between selectable objects.
• Press left mouse button to select an appropriate object to the dialog box.

For more details, please refer to the "Functionality common for OCC and VTK viewers" chapter of the GUI module's documentation.
