Describes functions to build draft
prism topologies from basis shape surfaces. These can be depressions or protrusions.
The semantics of draft prism feature creation is based on the
construction of shapes:

	A face Pbase is selected in the shape Sbase to serve as the basis for the draft prism. The draft will be defined by the angle Angle and Fuse offers a choice between:

void	Init (const TopoDS_Shape &Sbase, const TopoDS_Face &Pbase, const TopoDS_Face &Skface, const Standard_Real Angle, const Standard_Integer Fuse, const Standard_Boolean Modify)
	Initializes this algorithm for building draft prisms along surfaces. A face Pbase is selected in the basis shape Sbase to serve as the basis from the draft prism. The draft will be defined by the angle Angle and Fuse offers a choice between:
void	Add (const TopoDS_Edge &E, const TopoDS_Face &OnFace)
	Indicates that the edge <E> will slide on the face <OnFace>. Raises ConstructionError if the face does not belong to the basis shape, or the edge to the prismed shape.
void	Perform (const Standard_Real Height)
void	Perform (const TopoDS_Shape &Until)
void	Perform (const TopoDS_Shape &From, const TopoDS_Shape &Until)
	Assigns one of the following semantics
void	PerformUntilEnd ()
	Realizes a semi-infinite prism, limited by the position of the prism base.
void	PerformFromEnd (const TopoDS_Shape &FUntil)
	Realizes a semi-infinite prism, limited by the face Funtil.
void	PerformThruAll ()
	Builds an infinite prism. The infinite descendants will not be kept in the result.
void	PerformUntilHeight (const TopoDS_Shape &Until, const Standard_Real Height)
	Assigns both a limiting shape, Until from TopoDS_Shape, and a height, Height at which to stop generation of the prism feature.
void	Curves (TColGeom_SequenceOfCurve &S)
Handle_Geom_Curve	BarycCurve ()
void	BossEdges (const Standard_Integer sig)
	Determination of TopEdges and LatEdges. sig = 1 -> TopEdges = FirstShape of the DPrism sig = 2 -> TOpEdges = LastShape of the DPrism
const TopTools_ListOfShape &	TopEdges ()
	Returns the list of TopoDS Edges of the top of the boss.
const TopTools_ListOfShape &	LatEdges ()
	Returns the list of TopoDS Edges of the bottom of the boss.

Detailed Description

along a length
up to a limiting face
from a limiting face to a height.
The shape defining construction of the draft prism feature can be
either the supporting edge or the concerned area of a face.
In case of the supporting edge, this contour can be attached to a
face of the basis shape by binding. When the contour is bound to this
face, the information that the contour will slide on the face
becomes available to the relevant class methods.
In case of the concerned area of a face, you could, for example, cut
it out and move it to a different height which will define the
limiting face of a protrusion or depression.

removing matter with a Boolean cut using the setting 0
adding matter with Boolean fusion using the setting 1.
The sketch face Skface serves to determine the type of
operation. If it is inside the basis shape, a local
operation such as glueing can be performed.
