Am I able to restrict not to write Points data in IGES file while writing?

Hi Roman,
Thanks for your reply....
I'm very sorry If You are struggling to understand my english......
Actually I am calling the SaveIGES(InteractiveContext) to save the file in the editor as IGES file.....But I'm getting points data also in that IGES file...
But I don't want to have points data in that file...
The function to read a file and convert it into shape is as follows...
void AppDoc::Read(TopoDS_Shape& aShape, const Standard_CString aFileName)
{
OSD_Path aFile(aFileName);

Handle(StlMesh_Mesh) aSTLMesh = RWStl::ReadFile(aFile);
Standard_Integer NumberDomains = aSTLMesh->NbDomains();
Standard_Integer iND;
gp_XYZ p1, p2, p3;
TopoDS_Vertex Vertex1, Vertex2, Vertex3;
TopoDS_Face AktFace;
TopoDS_Wire AktWire;
BRepBuilderAPI_Sewing aSewingTool;
Standard_Real x1, y1, z1;
Standard_Real x2, y2, z2;
Standard_Real x3, y3, z3;

aSewingTool.Init(1.0e-06,Standard_True);

TopoDS_Compound aComp;
BRep_Builder BuildTool;
BuildTool.MakeCompound( aComp );

StlMesh_MeshExplorer aMExp (aSTLMesh);

for (iND=1;iND<=NumberDomains;iND++)
{
for (aMExp.InitTriangle (iND); aMExp.MoreTriangle (); aMExp.NextTriangle ())
{
aMExp.TriangleVertices (x1,y1,z1,x2,y2,z2,x3,y3,z3);
p1.SetCoord(x1,y1,z1);
p2.SetCoord(x2,y2,z2);
p3.SetCoord(x3,y3,z3);

if ((!(p1.IsEqual(p2,0.0))) && (!(p1.IsEqual(p3,0.0))))
{
Vertex1 = BRepBuilderAPI_MakeVertex(p1);
Vertex2 = BRepBuilderAPI_MakeVertex(p2);
Vertex3 = BRepBuilderAPI_MakeVertex(p3);

AktWire = BRepBuilderAPI_MakePolygon( Vertex1, Vertex2, Vertex3, Standard_True);

if( !AktWire.IsNull())
{
AktFace = BRepBuilderAPI_MakeFace( AktWire);
if(!AktFace.IsNull())
BuildTool.Add( aComp, AktFace );//Adding only faces
}
}
}
}
aSTLMesh->Clear();

aSewingTool.Load( aComp );
aSewingTool.Perform();
aShape = aSewingTool.SewedShape();
if ( aShape.IsNull() )
aShape = aComp;
}

In the above code I'm adding only faces to TopoDS_Compound. Eventhough the vertices data is writing into IGES file....

Please can you help me to write the data without vertices data...

Thanks
