This tool creates a surface from two, three or four boundary edges. Three different filling styles are available: Curved, Coons, Stretch. The tool creates a smooth transition between the boundary edges.


  1. Press the BSplineSurf.svg Fill boundary curves button.
  2. Select edges in the 3D-view. The edges must connect together in order to give a closed profile.
  3. Set options and press OK.



DataFill Type: The applied filling algorithm

  • Curved – the style with the most rounded patches.
  • Coons – a rounded style with less depth than Curved
  • Stretch – the style with the flattest patches


It is not possible to apply additional constraints to the surface.
