Summary	0024094: Issure by option of BRepAlgoAPI_Section
Description	At attached Face and the plane of a specific position, the intersection results of BRepAlgoAPI_Section differ by option of ComputePCurveOn and Approximation.
Steps To Reproduce	Draw[1]> pload ALL 1 Draw[2]> restore face.brep a a Draw[3]> plane p 183.6 0 0 1 0 0 0 1 0 Draw[4]> mkface f p Draw[5]> bsection result1 a f Draw[6]> explode result1 result1_1 Draw[7]> bsection result2 a f -na Draw[8]> explode result2 result2_1 Draw[9]> bsection result3 a f -n2d2 Draw[10]> explode result3 Draw[11]> bsection result4 a f -n2d Draw[12]> explode result4 Draw[13]> bsection result5 a f -n2d -na Draw[14]> explode result5 result5_1 Draw[15]>
Additional information and documentation updates	Method Standard_Boolean BOPInt_Context::IsValidBlockForFaces (const Standard_Real aT1, const Standard_Real aT2, const IntTools_Curve& aC, const TopoDS_Face& aF1, const TopoDS_Face& aF2, const Standard_Real aTol) To conclude that the curve is valid for the face checking only 2d curve is not enough. Also, it is necessary to check the 3d curve.
Tags	No tags attached.
