Build()

void GeomFill_Sweep::Build	(	const occ::handle< GeomFill_SectionLaw > &	Section,
		const GeomFill_ApproxStyle	Methode = GeomFill_Location,
		const GeomAbs_Shape	Continuity = GeomAbs_C2,
		const int	Degmax = 10,
		const int	Segmax = 30 )

Build the Sweeep Surface ApproxStyle defines Approximation Strategy.

• GeomFill_Section : The composed Function : Location X Section is directly approximated.
• GeomFill_Location : The location law is approximated, and the SweepSurface is build algebric composition of approximated location law and section law This option is Ok, if Section.Surface() methode is effective. Continuity : The continuity in v waiting on the surface Degmax : The maximum degree in v required on the surface Segmax : The maximum number of span in v required on the surface

raise If Domain are infinite or Profile not set.

ErrorOnRestriction()

void GeomFill_Sweep::ErrorOnRestriction	(	const bool	IsFirst,
		double &	UError,
		double &	VError ) const

Gets the Approximation error.

Gets the Approximation error.

ErrorOnTrace()

void GeomFill_Sweep::ErrorOnTrace	(	const int	IndexOfTrace,
		double &	UError,
		double &	VError ) const

Gets the Approximation error.

ExchangeUV()

bool GeomFill_Sweep::ExchangeUV

(

)

const

returns true if sections are U-Iso This can be produce in some cases when <WithKpart> is True.

IsDone()

bool GeomFill_Sweep::IsDone

(

SetDomain()

void GeomFill_Sweep::SetDomain	(	const double	First,
		const double	Last,
		const double	SectionFirst,
		const double	SectionLast )

Set parametric information [<First>, <Last>] Sets the parametric bound of the sweeping surface to build. <SectionFirst>, <SectionLast> gives corresponding bounds parameter on the section law of <First> and <Last>

V-Iso on Sweeping Surface S(u,v) is defined by Location(v) and Section(w) where w = SectionFirst + (v - First) / (Last-First)

• (SectionLast - SectionFirst)

By default w = v, and First and Last are given by First and Last parameter stored in LocationLaw.

SetForceApproxC1()

void GeomFill_Sweep::SetForceApproxC1

(

const bool

ForceApproxC1

)

Set the flag that indicates attempt to approximate a C1-continuous surface if a swept surface proved to be C0.

SetTolerance()

void GeomFill_Sweep::SetTolerance	(	const double	Tol3d,
		const double	BoundTol = 1.0,
		const double	Tol2d = 1.0e-5,
		const double	TolAngular = 1.0 )

Set Approximation Tolerance Tol3d : Tolerance to surface approximation Tol2d : Tolerance used to perform curve approximation Normally the 2d curve are approximated with a tolerance given by the resolution method define in <LocationLaw> but if this tolerance is too large Tol2d is used. TolAngular : Tolerance (in radian) to control the angle between tangents on the section law and tangent of iso-v on approximated surface.
