An interface class for 2D fillets. Open CASCADE provides two algorithms for 2D fillets: ChFi2d_Builder - it constructs a fillet or chamfer for linear and circular edges of a face. ChFi2d_FilletAPI - it encapsulates two algorithms: ChFi2d_AnaFilletAlgo - analytical constructor of the fillet. It works only for linear and circular edges, having a common point. ChFi2d_FilletAlgo - iteration recursive method constructing the fillet edge for any type of edges including ellipses and b-splines. The edges may even have no common point. More...

| ChFi2d_FilletAPI () | |
| An empty constructor of the fillet algorithm. Call a method Init() to initialize the algorithm before calling of a Perform() method. More... | |
| ChFi2d_FilletAPI (const TopoDS_Wire &theWire, const gp_Pln &thePlane) | |
| A constructor of a fillet algorithm: accepts a wire consisting of two edges in a plane. More... | |
| ChFi2d_FilletAPI (const TopoDS_Edge &theEdge1, const TopoDS_Edge &theEdge2, const gp_Pln &thePlane) | |
| A constructor of a fillet algorithm: accepts two edges in a plane. More... | |
| void | Init (const TopoDS_Wire &theWire, const gp_Pln &thePlane) |

| Standard_Boolean | Perform (const Standard_Real theRadius) |
| Constructs a fillet edge. Returns true if at least one result was found. More... | |
| Standard_Integer | NbResults (const gp_Pnt &thePoint) |
| Returns number of possible solutions. <thePoint> chooses a particular fillet in case of several fillets may be constructed (for example, a circle intersecting a segment in 2 points). Put the intersecting (or common) point of the edges. More... | |
| TopoDS_Edge | Result (const gp_Pnt &thePoint, TopoDS_Edge &theEdge1, TopoDS_Edge &theEdge2, const Standard_Integer iSolution=-1) |
| Returns result (fillet edge, modified edge1, modified edge2), nearest to the given point <thePoint> if iSolution == -1 <thePoint> chooses a particular fillet in case of several fillets may be constructed (for example, a circle intersecting a segment in 2 points). Put the intersecting (or common) point of the edges. More... | |

ChFi2d_FilletAlgo - iteration recursive method constructing the fillet edge for any type of edges including ellipses and b-splines. The edges may even have no common point.
The algorithms ChFi2d_AnaFilletAlgo and ChFi2d_FilletAlgo may be used directly or via this ChFi2d_FilletAPI class. This class chooses an appropriate algorithm analyzing the arguments (a wire or two edges).
