package ChFi2d
---Purpose: This package contains the algorithms used to build
-- fillets or chamfers on planar wire.

is
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
