Shape Healing

Hi

I'm using OCC 4.0 and I want to use shape healing to fix bad shapes.

I used samples provided in Shape healing user's guide to fix edges, wires, etc...
This is a part of the code that fixes Curves3D and edges order in wires (to illustrate my questions).

while (ShapeExplorer.More())
{

CurrentFaceShape = ShapeExplorer.Current();
Face = TopoDS::Face(CurrentFaceShape);
FaceExplorer.Init(CurrentFaceShape, TopAbs_EDGE);

while(FaceExplorer.More())
{
ShapeFix_Edge FixEdge;
Edge = TopoDS::Edge(FaceExplorer.Current());
if(!EdgeAnalysis.HasCurve3d(Edge))
FixEdge.FixAddCurve3d(Edge);

FaceExplorer.Next();
}

WireExplorer.Init(CurrentFaceShape, TopAbs_WIRE);

while(WireExplorer.More())
{
Wire = TopoDS::Wire(WireExplorer.Current());

ShapeFix_Wire WireFix(Wire, Face, Precision);
ShapeAnalysis_Wire WireAnalysis(Wire, Face, Precision);

if(WireAnalysis.CheckOrder())
WireFix.FixReorder();

Wire = WireFix.Wire();
WireExplorer.Next();
}
ShapeExplorer.Next();
}

At the end "Edge" contains my fixed edge, and "Wire" my fixed wires.

My questions :

1 - Is it possible to replace the bad edges and wires in the original shape with the fixed ones using a simple function (didn't find such functions in help :-( )? or do I have to reconstruct a shape using BRepBuilder in a Compound, face by face ?

2 - If I have to rebuild a Fixed shape using BRepBuilder face by face, how can I Make a clean and fixed face from :

- My Old Face (from TopExplorer)
- My new edges
- My new wires

to add if to my fixed shape ?

Thanks in advance,
Eric
