static void	Add (const Adaptor3d_Curve &C, const Standard_Real Tol, Bnd_Box &B)
	Adds to the bounding box B the curve C B is then enlarged by the tolerance value Tol. Note: depending on the type of curve, one of the following representations of the curve C is used to include it in the bounding box B:
static void	Add (const Adaptor3d_Curve &C, const Standard_Real U1, const Standard_Real U2, const Standard_Real Tol, Bnd_Box &B)
	Adds to the bounding box B the curve C the arc of the curve C limited by the two parameter values P1 and P2. Note: depending on the type of curve, one of the following representations of the curve C is used to include it in the bounding box B:

static void BndLib_Add3dCurve::Add	(	const Adaptor3d_Curve &	C,
		const Standard_Real	Tol,
		Bnd_Box &	B
	)		`[static]`

an exact representation if C is built from a line, a circle or a conic curve,
the poles of the curve if C is built from a Bezier curve or a BSpline curve,
if not, the points of an approximation of the curve C.
Warning
C is an adapted curve, that is, an object which is an interface between:
the services provided by a 3D curve from the package Geom
and those required of the curve by the computation algorithm.
The adapted curve is created in the following way:
Handle(Geom_Curve) mycurve = ... ;
GeomAdaptor_Curve C(mycurve);
The bounding box B is then enlarged by adding it:
Bnd_Box B;
// ...
Standard_Real Tol = ... ;
Add3dCurve::Add ( C, Tol, B );
Exceptions
Standard_Failure if the curve is built from:
a Geom_Line, or
a Geom_Parabola, or
a Geom_Hyperbola,
and P1 and P2 are either two negative infinite real
numbers, or two positive infinite real numbers.
