Hi Fabian

my sourcecode :

I have in entry a TopoDS_Face: F and 3 TopoDS_Wire: Wtop, Wbottom, and Whole

BRepAPI_MakeFace mkFace(F);

mkFace.Add(Wtop);

mkFace.Add(Wbottom);

mkFace.Add(Whole);

mkFace.Build();

if (mkFace.IsDone())
{
TopoDS_Face result = mkFace.Face();
}

I attached the result.

Can you said me the problem??
Thanks

Hi Roseline,

by the image attached it seems that the result face has orientation problem.

Try the ShapeFix_Face:

ShapeFix_Face sff( result );
sff.FixOrientation();
sff.Perform();
TopoDS_Face fixedFace = sff.Face();

Regards,
Gabriel
