Problem with OCBRepFilletAPI_MakeFillet

Thank you for your reply. I made a wire from those 2 edges but it still dosen't work. HasResult and IsDone functions always return false. It looks like problem with add function of BRepFilletAPI_MakeFillet or maybe I'm doing something incorrect way? My code is below.

BRepBuilderAPI_MakeEdge edgeMaker1 = new BRepBuilderAPI_MakeEdge(new gp_Pnt(0, 0, 0), new gp_Pnt(10, 0, 0)); //
BRepBuilderAPI_MakeEdge edgeMaker2 = new BRepBuilderAPI_MakeEdge(new gp_Pnt(10, 0, 0), new gp_Pnt(10, 10, 0)); //
BRepBuilderAPI_MakeWire wireMaker = new BRepBuilderAPI_MakeWire();

wireMaker.Add(edgeMaker1.Edge());
wireMaker.Add(edgeMaker2.Edge());

BRepFilletAPI_MakeFillet filleter = new BRepFilletAPI_MakeFillet(wireMaker.Shape(), OCChFi3d_FilletShape.ChFi3d_Polynomial);

if (wireMaker.IsDone()) {

TopExp_Explorer explorer = new TopExp_Explorer(wireMaker.Shape(), TopAbs_ShapeEnum.TopAbs_EDGE, TopAbs_ShapeEnum.TopAbs_SHAPE);
for (; explorer.More(); explorer.Next()) {

TopoDS_Shape shape = explorer.Current();
if (shape.ShapeType() == TopAbs_ShapeEnum.TopAbs_EDGE) {
TopoDS_Edge edge = TopoDS.Edge(shape);
filleter.Add(3, edge);

}

}

}
int c = filleter.NbFaultyVertices(); // = 0

TopTools_ListOfShape lOS = filleter.Generated(wireMaker.Shape());
if (lOS.IsEmpty()) {
// list of generated shapes is empty
}

if (filleter.HasResult()/* Allwys returns false */) {
int b = 0;
}

if (filleter.IsDone()/* always returns false*/) {

userControl11.Display(new AIS_Shape(filleter.BadShape()));

userControl11.Display(new AIS_Shape(filleter.Shape())); //if outside this block makes program crashes
}
