Describes functions to build prism features.
These can be depressions or protrusions.
The semantics of prism feature creation is
based on the construction of shapes:

	BRepFeat_MakePrism ()
	Builds a prism by projecting a wire along the face of a shape. Initializes the prism class.
	BRepFeat_MakePrism (const TopoDS_Shape &Sbase, const TopoDS_Shape &Pbase, const TopoDS_Face &Skface, const gp_Dir &Direction, const Standard_Integer Fuse, const Standard_Boolean Modify)
	Builds a prism by projecting a wire along the face of a shape. a face Pbase is selected in the shape Sbase to serve as the basis for the prism. The orientation of the prism will be defined by the vector Direction. Fuse offers a choice between:
void	Init (const TopoDS_Shape &Sbase, const TopoDS_Shape &Pbase, const TopoDS_Face &Skface, const gp_Dir &Direction, const Standard_Integer Fuse, const Standard_Boolean Modify)
	Initializes this algorithm for building prisms along surfaces. A face Pbase is selected in the shape Sbase to serve as the basis for the prism. The orientation of the prism will be defined by the vector Direction. 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 Length)
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. All other faces extend infinitely.
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 Length)
	Assigns both a limiting shape, Until from TopoDS_Shape, and a height, Length at which to stop generation of the prism feature.
void	Curves (TColGeom_SequenceOfCurve &S)
	Returns the list of curves S parallel to the axis of the prism.
Handle_Geom_Curve	BarycCurve ()
	Generates a curve along the center of mass of the primitive.

Detailed Description

along a length
up to a limiting face
from a limiting face to a height.
The shape defining construction of the 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.

Constructor & Destructor Documentation

BRepFeat_MakePrism::BRepFeat_MakePrism ( )

BRepFeat_MakePrism::BRepFeat_MakePrism	(	const TopoDS_Shape &	Sbase,
		const TopoDS_Shape &	Pbase,
		const TopoDS_Face &	Skface,
		const gp_Dir &	Direction,
		const Standard_Integer	Fuse,
		const Standard_Boolean	Modify
	)

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.
Exceptions
Standard_ConstructionError if the face
does not belong to the basis or the prism shape.
