void BRepFill_Sweep::Build ( TopTools_MapOfShape ReversedEdges,
BRepFill_DataMapOfShapeHArray2OfShape Tapes,
BRepFill_DataMapOfShapeHArray2OfShape Rails,
const BRepFill_TransitionStyle  Transition = BRepFill_Modified,
const GeomAbs_Shape  Continuity = GeomAbs_C2,
const GeomFill_ApproxStyle  Approx = GeomFill_Location,
const Standard_Integer  Degmax = 11,
const Standard_Integer  Segmax = 30 
)

Build the Sweeep Surface Transition define Transition strategy Approx define Approximation Strategy.

  • GeomFill_Section : The composed Function Location X Section is directly approximed.
  • GeomFill_Location : The location law is approximed, and the SweepSurface is bulid algebric composition of approximed 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 requiered on the surface Segmax : The maximum number of span in v requiered on the surface.
Standard_Real BRepFill_Sweep::ErrorOnSurface ( ) const

Get the Approximation error.

Handle< TopTools_HArray2OfShape > BRepFill_Sweep::InterFaces ( ) const
Standard_Boolean BRepFill_Sweep::IsDone ( ) const

Say if the Shape is Build.

void BRepFill_Sweep::SetAngularControl ( const Standard_Real  AngleMin = 0.01,
const Standard_Real  AngleMax = 6.0 
)

Tolerance To controle Corner management.

If the discontinuity is lesser than <AngleMin> in radian The Transition Performed will be alway "Modified"

void BRepFill_Sweep::SetBounds ( const TopoDS_Wire FirstShape,
const TopoDS_Wire LastShape 
)
void BRepFill_Sweep::SetForceApproxC1 ( const Standard_Boolean  ForceApproxC1)

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

void BRepFill_Sweep::SetTolerance ( const Standard_Real  Tol3d,
const Standard_Real  BoundTol = 1.0,
const Standard_Real  Tol2d = 1.0e-5,
const Standard_Real  TolAngular = 1.0e-2 
)

Set Approximation Tolerance Tol3d : Tolerance to surface approximation Tol2d : Tolerance used to perform curve approximation Normaly the 2d curve are approximated with a tolerance given by the resolution on support surfaces, but if this tolerance is too large Tol2d is used. TolAngular : Tolerance (in radian) to control the angle beetween tangents on the section law and tangent of iso-v on approximed surface.

TopoDS_Shape BRepFill_Sweep::Shape ( ) const

returns the Sweeping Shape
