 BRepFilletAPI_MakeFillet2d ()
 Initializes an empty algorithm for computing fillets and
chamfers. The face on which the fillets and
chamfers are built is defined using the Init function.
The vertices on which fillets or chamfers are built are
defined using the AddFillet or AddChamfer function.
Warning
The status of the initialization, as given by the Status
function, can be one of the following:

 BRepFilletAPI_MakeFillet2d (const TopoDS_Face &F)
 Initializes an algorithm for computing fillets and chamfers on the face F.
The vertices on which fillets or chamfers are built are
defined using the AddFillet or AddChamfer function.
Warning
The status of the initialization, as given by the Status
function, can be one of the following:

void Init (const TopoDS_Face &F)
 Initializes this algorithm for constructing fillets or
chamfers with the face F.
Warning
The status of the initialization, as given by the Status
function, can be one of the following:

void Init (const TopoDS_Face &RefFace, const TopoDS_Face &ModFace)
 This initialize method allow to init the builder
from a face <RefFace> and another face <ModFace>
which derive from <RefFace>. This is usefull to
modify a fillet or a chamfer already created on
<ModFace> .

TopoDS_Edge AddFillet (const TopoDS_Vertex &V, const Standard_Real Radius)
 Adds a fillet of radius Radius between the two edges
adjacent to the vertex V on the face modified by this
algorithm. The two edges do not need to be rectilinear.
This function returns the fillet and builds the resulting face.
Warning
The status of the construction, as given by the Status
function, can be one of the following:

TopoDS_Edge ModifyFillet (const TopoDS_Edge &Fillet, const Standard_Real Radius)
 Assigns the radius Radius to the fillet Fillet already
built on the face modified by this algorithm.
This function returns the new fillet and modifies the existing face.
Warning
The status of the construction, as given by the Status
function, can be one of the following:

TopoDS_Vertex RemoveFillet (const TopoDS_Edge &Fillet)
 Removes the fillet Fillet already built on the face
modified by this algorithm.
This function returns the vertex connecting the two
adjacent edges of Fillet and modifies the existing face.
Warning

TopoDS_Edge AddChamfer (const TopoDS_Edge &E1, const TopoDS_Edge &E2, const Standard_Real D1, const Standard_Real D2)
 Adds a chamfer on the face modified by this algorithm
between the two adjacent edges E1 and E2, where
the extremities of the chamfer are on E1 and E2 at
distances D1 and D2 respectively
In cases where the edges are not rectilinear, distances
are measured using the curvilinear abscissa of the
edges and the angle is measured with respect to the
tangent at the corresponding point.
The angle Ang is given in radians.
This function returns the chamfer and builds the resulting face.

TopoDS_Edge AddChamfer (const TopoDS_Edge &E, const TopoDS_Vertex &V, const Standard_Real D, const Standard_Real Ang)
 Adds a chamfer on the face modified by this algorithm
between the two edges connected by the vertex V,
where E is one of the two edges. The chamfer makes
an angle Ang with E and one of its extremities is on
E at distance D from V.
In cases where the edges are not rectilinear, distances
are measured using the curvilinear abscissa of the
edges and the angle is measured with respect to the
tangent at the corresponding point.
The angle Ang is given in radians.
This function returns the chamfer and builds the resulting face.
Warning
The status of the construction, as given by the Status function, can
be one of the following:

TopoDS_Edge ModifyChamfer (const TopoDS_Edge &Chamfer, const TopoDS_Edge &E1, const TopoDS_Edge &E2, const Standard_Real D1, const Standard_Real D2)
 Modifies the chamfer Chamfer on the face modified
by this algorithm, where:
E1 and E2 are the two adjacent edges on which
Chamfer is already built; the extremities of the new
chamfer are on E1 and E2 at distances D1 and D2 respectively.

TopoDS_Edge ModifyChamfer (const TopoDS_Edge &Chamfer, const TopoDS_Edge &E, const Standard_Real D, const Standard_Real Ang)

by this algorithm, where:
E is one of the two adjacent edges on which
Chamfer is already built; the new chamfer makes
an angle Ang with E and one of its extremities is
on E at distance D from the vertex on which the chamfer is built.
In cases where the edges are not rectilinear, the
distances are measured using the curvilinear abscissa
of the edges and the angle is measured with respect
to the tangent at the corresponding point.
The angle Ang is given in radians.
This function returns the new chamfer and modifies the existing face.
Warning
The status of the construction, as given by the Status
function, can be one of the following:

modified by this algorithm.

adjacent edges of Chamfer and modifies the existing face.

belong to the initial face.

const TopoDS_EdgeBasisEdge (const TopoDS_Edge &E) const
 Returns the basis edge on the face modified by this
algorithm from which the chamfered or filleted edge E is
