Detailed Description

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:

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.

Constructor & Destructor Documentation

BRepFeat_MakeDPrism::BRepFeat_MakeDPrism	(	const TopoDS_Shape &	Sbase,
		const TopoDS_Face &	Pbase,
		const TopoDS_Face &	Skface,
		const Standard_Real	Angle,
		const Standard_Integer	Fuse,
		const Standard_Boolean	Modify
	)

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:

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.
//! Initializes the draft prism class

 Initializes this algorithm for building draft prisms along surfaces. <br>

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:

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.

void BRepFeat_MakeDPrism::PerformUntilEnd ( )

Realizes a semi-infinite prism, limited by the position of the prism base.

void BRepFeat_MakeDPrism::PerformUntilHeight	(	const TopoDS_Shape &	Until,

 Assigns both a limiting shape, Until from <br>

TopoDS_Shape, and a height, Height at which to stop
generation of the prism feature.
