Member Function Documentation

AddWire()

void BRepOffsetAPI_MakeOffsetFix::AddWire

(

const TopoDS_Wire &

Spine

)

Initializes the algorithm to construct parallels to the wire Spine.

Referenced by Part::ExtrusionHelper::createTaperedPrismOffset(), and Part::TopoShape::makeOffset2D().

Build()

void BRepOffsetAPI_MakeOffsetFix::Build

(

)

Builds the resulting shape (redefined from MakeShape).

Generated()

const TopTools_ListOfShape & BRepOffsetAPI_MakeOffsetFix::Generated ( const TopoDS_Shape &  S )

virtual

returns a list of the created shapes from the shape .

Init() [1/2]

void BRepOffsetAPI_MakeOffsetFix::Init	(	const GeomAbs_JoinType	Join = GeomAbs_Arc,
		const Standard_Boolean	IsOpenResult = Standard_False
	)

Initialize the evaluation of Offsetting.

Init() [2/2]

void BRepOffsetAPI_MakeOffsetFix::Init	(	const TopoDS_Face &	Spine,
		const GeomAbs_JoinType	Join = GeomAbs_Arc,
		const Standard_Boolean	IsOpenResult = Standard_False
	)

Initializes the algorithm to construct parallels to the spine Spine.

Join defines the type of parallel generated by the salient vertices of the spine. The default type is GeomAbs_Arc where the vertices generate sections of a circle. If join type is GeomAbs_Intersection, the edges that intersect in a salient vertex generate the edges prolonged until intersection.

IsDeleted()

Standard_Boolean BRepOffsetAPI_MakeOffsetFix::IsDeleted ( const TopoDS_Shape &  S )

virtual

Returns true if the shape S has been deleted.

IsDone()

Standard_Boolean BRepOffsetAPI_MakeOffsetFix::IsDone ( ) const

virtual

Modified()

const TopTools_ListOfShape & BRepOffsetAPI_MakeOffsetFix::Modified ( const TopoDS_Shape &  S )

virtual

Returns the list of shapes modified from the shape .

Perform()

void BRepOffsetAPI_MakeOffsetFix::Perform	(	const Standard_Real	Offset,
		const Standard_Real	Alt = 0.0
	)

Computes a parallel to the spine at distance Offset and at an altitude Alt from the plane of the spine in relation to the normal to the spine.

Exceptions: StdFail_NotDone if the offset is not built.

Referenced by Part::ExtrusionHelper::createTaperedPrismOffset(), and Part::TopoShape::makeOffset2D().

Replace()

TopoDS_Shape BRepOffsetAPI_MakeOffsetFix::Replace	(	GeomAbs_CurveType	type,
		const TopoDS_Shape &	S
	)		const

Replaces the given curve type with a B-Spline.

Input shape must be a wire or a compound of wires

Shape()

const TopoDS_Shape & BRepOffsetAPI_MakeOffsetFix::Shape ( )

virtual

Returns a shape built by the shape construction algorithm.

Raises exception StdFail_NotDone if the shape was not built.
