Hi all,

When SetNonManifoldMode of BRepOffsetAPI_Sewing is set as Standard_True , the NbFreeEdges will get wrong result. I use the ShapeAnalysis_Shell to check the free edges of the sewed shell, it gets the correct result.
I am not sure whether it's a bug of sewing API. I try to read through each detailed coded about the NonManifold sewing, but it's too complex to understand.
