BRepBuilderAPI_MakeFace precision

Thanks Pawel,

I will try this. Its my (limited) understanding that ShapeFix_ShapeTolerance alters shape? Is this true?

For various reasons I am not allwoed to alter the data i simply want to treat it as a plane with a given tolerance.

Stephen

double myTolerance = 0.00001; // vary this
TopoDS_Vertex v1 = newVertex(0,0,0);
TopoDS_Vertex v2 = newVertex(0,1,0);
TopoDS_Vertex v3 = newVertex(1,1,0);
TopoDS_Vertex v4 = newVertex(1,1,0.0001);

TopoDS_Edge e1 = newEdge(v1,v2);
TopoDS_Edge e2 = newEdge(v2,v3);
TopoDS_Edge e3 = newEdge(v3,v4);
TopoDS_Edge e4 = newEdge(v4,v1);

BRepBuilderAPI_MakeWire mWire(e1,e2,e3,e4);

// create a tolerance object
ShapeFix_ShapeTolerance FTol;
// get the wide
TopoDS_Wire wire = mWire.Wire();
// set the tolerance for this shape.
FTol.SetTolerance(wire, myTolerance ,TopAbs_WIRE);

// make the face with this tolerance
BRepBuilderAPI_MakeFace mFace(wire);

if (mFace.IsDone())
{
cout << "Done" << endl;
}
else
{
cout << BRepBuilderAPI_NotPlanar << endl;
cout << mFace.Error() << endl;
cout << "Failed" << endl;
}
