package ShapeUpgrade
---Purpose: This package provides tools
-- for splitting and converting shapes by some criteria. It
-- provides modifications of the kind when one topological
-- object can be converted or splitted to several ones. In
-- particular this package contains high level API classes which perform:
-- converting geometry of shapes up to given continuity,
-- splitting revolutions by U to segments less than given value,
-- converting to beziers,
-- splitting closed faces.

---Purpose: API Class for convering curves to beziers.

C0BSplineToSequenceOfC1BSplineCurve (BS : BSplineCurve from Geom;
seqBS: out HSequenceOfBoundedCurve from TColGeom)
returns Boolean;
C0BSplineToSequenceOfC1BSplineCurve (BS : BSplineCurve from Geom2d;
seqBS: out HSequenceOfBoundedCurve from TColGeom2d)
returns Boolean;
--- Purpose: Converts C0 B-Spline curve into sequence of C1 B-Spline curves.
-- This method splits B-Spline at the knots with multiplicities
-- equal to degree, i.e. unlike method
-- GeomConvert::C0BSplineToArrayOfC1BSplineCurve this one does not
-- use any tolerance and therefore does not change the geometry of
-- B-Spline.
-- Returns True if C0 B-Spline was successfully splitted, else
-- returns False (if BS is C1 B-Spline).
