-package ChFi2d
-
- ---Purpose: This package contains the algorithms used to build
- -- fillets or chamfers on planar wire.
- --
- -- This package 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.
- -- ChFi2d_ChamferAPI - an algoroithm for construction of chamfers
- -- between two linear edges of a plane.
- --
- -- The algorithms ChFi2d_AnaFilletAlgo and ChFi2d_FilletAlgo may be used directly
- -- or via the interface class ChFi2d_FilletAPI.

- enumeration ConstructionError is
- ---Purpose: error that can occur during the
- -- fillet construction on planar wire
- NotPlanar,
- ---Purpose: the face is not planar
- NoFace,
- ---Purpose: the face is null
- InitialisationError,
- ---Purpose: the two faces used for the initialisation are
- -- uncompatible.
- ParametersError,
- ---Purpose: the parameters as distances or angle for
- -- chamfer are less or equal to zero.
- Ready,
- ---Purpose: the initialization has been succesfull.
- IsDone,
- ComputationError,
- ---Purpose: the algorithm could not find a solution.
- ConnexionError,
- ---Purpose: the vertex given to locate the fillet or the
- -- chamfer is not connected to 2 edges.
- TangencyError,
- ---Purpose: the two edges connected to the vertex are tangent.
-
-
- FirstEdgeDegenerated,
- ---Purpose: the first edge is degenerated.
- LastEdgeDegenerated,
- ---Purpose: the last edge is degenerated.
- BothEdgesDegenerated,
- ---Purpose: the two edges are degenerated.
- NotAuthorized
- ---Purpose: One or the two edges connected to the vertex
- -- is a fillet or a chamfer
- -- One or the two edges connected to the vertex
- -- is not a line or a circle
