ChFi2d_FilletAPI Class Reference

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...

Detailed Description

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.

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).

Constructor & Destructor Documentation

ChFi2d_FilletAPI::ChFi2d_FilletAPI

(

)

ChFi2d_FilletAPI::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.

ChFi2d_FilletAPI::ChFi2d_FilletAPI	(	const TopoDS_Edge &	theEdge1,
		const TopoDS_Edge &	theEdge2,
		const gp_Pln &	thePlane

Member Function Documentation

void ChFi2d_FilletAPI::Init	(	const TopoDS_Wire &	theWire,
		const gp_Pln &	thePlane
	)

Initializes a fillet algorithm: accepts a wire consisting of two edges in a plane.

void ChFi2d_FilletAPI::Init	(	const TopoDS_Edge &	theEdge1,
		const TopoDS_Edge &	theEdge2,
		const gp_Pln &	thePlane
	)

Initializes a fillet algorithm: accepts two edges in a plane.

Standard_Integer ChFi2d_FilletAPI::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.

Standard_Boolean ChFi2d_FilletAPI::Perform

(

const Standard_Real

theRadius

)

Constructs a fillet edge. Returns true if at least one result was found.

TopoDS_Edge ChFi2d_FilletAPI::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.
