0030 //! This package contains the algorithms used to build
0031 //! fillets or chamfers on planar wire.
0032 //!
0033 //! This package provides two algorithms for 2D fillets:
0034 //! ChFi2d_Builder - it constructs a fillet or chamfer
0035 //! for linear and circular edges of a face.
0036 //! ChFi2d_FilletAPI - it encapsulates two algorithms:
0037 //! ChFi2d_AnaFilletAlgo - analytical constructor of the fillet.
0038 //! It works only for linear and circular edges,
0039 //! having a common point.
0040 //! ChFi2d_FilletAlgo - iteration recursive method constructing
0041 //! the fillet edge for any type of edges including
0042 //! ellipses and b-splines.
0043 //! The edges may even have no common point.
0044 //! ChFi2d_ChamferAPI - an algorithm for construction of chamfers
0045 //! between two linear edges of a plane.
0046 //!
0047 //! The algorithms ChFi2d_AnaFilletAlgo and ChFi2d_FilletAlgo may be used directly
0048 //! or via the interface class ChFi2d_FilletAPI.
