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.

Detailed Description

Constructs compound shapes with pipe features. These can be depressions or protrusions. The semantics of pipe 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 pipe 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_MakePipe() [1/2]

BRepFeat_MakePipe::BRepFeat_MakePipe

(

)

initializes the pipe class.

BRepFeat_MakePipe() [2/2]

BRepFeat_MakePipe::BRepFeat_MakePipe	(	const TopoDS_Shape &	Sbase,
		const TopoDS_Shape &	Pbase,
		const TopoDS_Face &	Skface,
		const TopoDS_Wire &	Spine,
		const int	Fuse,
		const bool	Modify )

A face Pbase is selected in the shape Sbase to serve as the basis for the pipe. It will be defined by the wire Spine. 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.

Member Function Documentation

Add()

void BRepFeat_MakePipe::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.

Curves()

void BRepFeat_MakePipe::Curves ( NCollection_Sequence< occ::handle< Geom_Curve > > & S )

		const TopoDS_Shape &	Pbase,
		const TopoDS_Face &	Skface,

Initializes this algorithm for adding pipes to shapes. A face Pbase is selected in the shape Sbase to serve as the basis for the pipe. It will be defined by the wire Spine. 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.
