Detailed Description

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:

Constructor & Destructor Documentation

◆ BRepFeat_MakePrism() [1/2]

BRepFeat_MakePrism::BRepFeat_MakePrism ( )

Builds a prism by projecting a wire along the face of a shape. Initializes the prism class.

◆ BRepFeat_MakePrism() [2/2]

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 
)

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:

  • 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.

Member Function Documentation

◆ Add()

void BRepFeat_MakePrism::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_MakePrism::BarycCurve ( )
virtual

Generates a curve along the center of mass of the primitive.

Implements BRepFeat_Form.

◆ Curves()

void BRepFeat_MakePrism::Curves ( TColGeom_SequenceOfCurve S)
virtual

Returns the list of curves S parallel to the axis of the prism.

Implements BRepFeat_Form.

◆ Init()

void BRepFeat_MakePrism::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:

  • 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.

◆ Perform() [1/3]

void BRepFeat_MakePrism::Perform ( const Standard_Real  Length)

◆ Perform() [2/3]

void BRepFeat_MakePrism::Perform ( const TopoDS_Shape Until)

◆ Perform() [3/3]

void BRepFeat_MakePrism::Perform ( const TopoDS_Shape From,
const TopoDS_Shape Until 
)

Assigns one of the following semantics.

  • to a height Length
  • 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_MakePrism::PerformFromEnd ( const TopoDS_Shape FUntil)

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

◆ PerformThruAll()

void BRepFeat_MakePrism::PerformThruAll ( )

Builds an infinite prism. The infinite descendants will not be kept in the result.

◆ PerformUntilEnd()

void BRepFeat_MakePrism::PerformUntilEnd ( )

Realizes a semi-infinite prism, limited by the position of the prism base. All other faces extend infinitely.

◆ PerformUntilHeight()

void BRepFeat_MakePrism::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.
