BRepFeat_RibSlot Class Reference

Provides functions to build mechanical features.
Mechanical features include ribs - protrusions and grooves (or slots) - depressions along
planar (linear) surfaces or revolution surfaces. The semantics of mechanical features is built
around giving thickness to a contour. This thickness can either be unilateral - on one side
of the contour - or bilateral - on both sides.
As in the semantics of form features, the thickness is defined by construction of shapes
in specific contexts. The development contexts differ, however,in case of mechanical features.
Here they include extrusion:

Public Member Functions
virtual DEFINE_STANDARD_ALLOC Standard_Boolean	IsDeleted (const TopoDS_Shape &F)
	Returns true if F a TopoDS_Shape of type edge or face has been deleted.
virtual const TopTools_ListOfShape &	Modified (const TopoDS_Shape &F)
	Returns the list of generated Faces F. This list may be empty.
virtual const TopTools_ListOfShape &	Generated (const TopoDS_Shape &S)
	Returns a list TopTools_ListOfShape of the faces S created in the shape.
const TopTools_ListOfShape &	FirstShape () const
	Returns the list of shapes created at the bottom of the created form. It may be an empty list.
const TopTools_ListOfShape &	LastShape () const
	Returns the list of shapes created at the top of the created form. It may be an empty list.
const TopTools_ListOfShape &	FacesForDraft () const
	Returns a list of the limiting and glueing faces generated by the feature. These faces did not originally exist in the basis shape. The list provides the information necessary for subsequent addition of a draft to a face. It may be an empty list. If a face has tangent edges, no draft is possible, and the tangent edges must subsequently be removed if you want to add a draft to the face.
const TopTools_ListOfShape &	NewEdges () const
	Returns a list of the limiting and glueing edges generated by the feature. These edges did not originally exist in the basis shape. The list provides the information necessary for subsequent addition of fillets. It may be an empty list.
const TopTools_ListOfShape &	TgtEdges () const
	Returns a list of the tangent edges among the limiting and glueing edges generated by the feature. These edges did not originally exist in the basis shape and are tangent to the face against which the feature is built. The list provides the information necessary for subsequent addition of fillets. It may be an empty list. If an edge is tangent, no fillet is possible, and the edge must subsequently be removed if you want to add a fillet.

void	UpdateDescendants (const Handle< BOP_HistoryCollector > &aBOP, const TopoDS_Shape &SResult, const Standard_Boolean SkipFace=Standard_False)
	Updates the data structures of descendant shapes during the glueing operation. Returns the modified, generated and deleted faces during the course of the glueing operation; furnishes the arguments of the resulting shape SResult using the builder B to determine the type of modification such as orientation and splitting; checks to see that the SResult belongs to the data structure of the original shape.
