Detailed Description

Describes algorithms for offsetting wires from a set of wires contained in a planar face. A MakeOffset object provides a framework for:

• defining the construction of an offset,
• implementing the construction algorithm, and
• consulting the result.

Constructor & Destructor Documentation

BRepOffsetAPI_MakeOffset::BRepOffsetAPI_MakeOffset

(

)

Constructs an algorithm for creating an empty offset.

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::BRepOffsetAPI_MakeOffset	(	const TopoDS_Wire &	Spine,
		const GeomAbs_JoinType	Join = GeomAbs_Arc,
		const Standard_Boolean	IsOpenResult = Standard_False

Member Function Documentation

void BRepOffsetAPI_MakeOffset::AddWire

(

const TopoDS_Wire &

Spine

)

Initializes the algorithm to construct parallels to the wire Spine.

virtual void BRepOffsetAPI_MakeOffset::Build ( )

virtual

Builds the resulting shape (redefined from MakeShape).

Reimplemented from BRepBuilderAPI_MakeShape.

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

virtual

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

Reimplemented from BRepBuilderAPI_MakeShape.

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.

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

Initialize the evaluation of Offseting.

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.
