Constructor & Destructor Documentation

◆ BRepOffsetAPI_MakeOffset() [1/3]

BRepOffsetAPI_MakeOffset::BRepOffsetAPI_MakeOffset ( )

Constructs an algorithm for creating an empty offset.

◆ BRepOffsetAPI_MakeOffset() [2/3]

BRepOffsetAPI_MakeOffset::BRepOffsetAPI_MakeOffset ( const TopoDS_Face Spine,
const GeomAbs_JoinType  Join = GeomAbs_Arc,
const Standard_Boolean  IsOpenResult = Standard_False 
)

Constructs an algorithm for creating an algorithm to build parallels to the spine Spine.

◆ BRepOffsetAPI_MakeOffset() [3/3]

Member Function Documentation

◆ AddWire()

void BRepOffsetAPI_MakeOffset::AddWire ( const TopoDS_Wire Spine)

Initializes the algorithm to construct parallels to the wire Spine.

◆ Build()

virtual void BRepOffsetAPI_MakeOffset::Build ( const Message_ProgressRange theRange = Message_ProgressRange())
overridevirtual

Builds the resulting shape (redefined from MakeShape).

Reimplemented from BRepBuilderAPI_MakeShape.

◆ ConvertFace()

static TopoDS_Face BRepOffsetAPI_MakeOffset::ConvertFace ( const TopoDS_Face theFace,
const Standard_Real  theAngleTolerance 
)
static

Converts each wire of the face into contour consisting only of arcs and segments. New 3D curves are built too.

◆ Generated()

virtual const TopTools_ListOfShape& BRepOffsetAPI_MakeOffset::Generated ( const TopoDS_Shape S)
overridevirtual

returns a list of the created shapes from the shape <S>.

Reimplemented from BRepBuilderAPI_MakeShape.

◆ Init() [1/2]

void BRepOffsetAPI_MakeOffset::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.

◆ Init() [2/2]

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

Initialize the evaluation of Offsetting.

◆ Perform()

void BRepOffsetAPI_MakeOffset::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.

◆ SetApprox()

void BRepOffsetAPI_MakeOffset::SetApprox ( const Standard_Boolean  ToApprox)

Set approximation flag for convertion input contours into ones consisting of 2D circular arcs and 2D linear segments only.
