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:

Constructor & Destructor Documentation

◆ BRepFeat_MakeDPrism() [1/2]

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 
)
inline

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

◆ Add()

void BRepFeat_MakeDPrism::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.

◆ BarycCurve()

Handle< Geom_Curve > BRepFeat_MakeDPrism::BarycCurve ( )
virtual

Implements BRepFeat_Form.

◆ BossEdges()

void BRepFeat_MakeDPrism::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 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:

  • 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.

const TopoDS_Shape Until

Assigns one of the following semantics.

  • to a height Height
  • to a face Until
  • from a face From to a height Until. Reconstructs the feature topologically according to the semantic option chosen.

◆ PerformFromEnd()

void BRepFeat_MakeDPrism::PerformFromEnd ( const TopoDS_Shape FUntil)

Realizes a semi-infinite prism, limited by the face Funtil.

◆ PerformThruAll()

void BRepFeat_MakeDPrism::PerformUntilHeight ( const TopoDS_Shape Until,
