	BRepOffsetAPI_MakeOffset ()
	Constructs an algorithm for creating an empty offset.

	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.

void	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.

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.
