class BasicCurve from IGESToBRep inherits CurveAndSurface from IGESToBRep
---Purpose : Provides methods to transfer basic geometric curves entities
-- from IGES to CASCADE.
-- These can be :
-- * Circular arc
-- * Conic arc
-- * Spline curve
-- * BSpline curve
-- * Line
-- * Copious data
-- * Point
-- * Transformation matrix

is
Create returns BasicCurve;
---Purpose : Creates a tool BasicCurve ready to run, with
-- epsilons set to 1.E-04, TheModeTopo to True, the
-- optimization of the continuity to False.
Create(CS : CurveAndSurface from IGESToBRep) returns BasicCurve;
---Purpose : Creates a tool BasicCurve ready to run and sets its
-- fields as CS's.
Create(eps : Real;
epsGeom : Real;
epsCoeff : Real;
mode : Boolean;
modeapprox : Boolean;
optimized : Boolean) returns BasicCurve;
---Purpose : Creates a tool BasicCurve ready to run.
TransferBasicCurve (me : in out;
start : IGESEntity from IGESData)
returns mutable Curve from Geom;
---Purpose : Transfert a IGESEntity which answer True to the
-- member : IGESToBRep::IsBasicCurve(IGESEntity). If this
-- Entity could not be converted, this member returns a NullEntity.
Transfer2dBasicCurve (me : in out;
start : IGESEntity from IGESData)
returns mutable Curve from Geom2d;
---Purpose : Transfert a IGESEntity which answer True to the
-- member : IGESToBRep::IsBasicCurve(IGESEntity).
-- The IGESEntity must be a curve UV and its associed TRSF must
-- be planar .If this Entity could not be converted, this member
-- returns a NullEntity.
