Detailed Description

The algorithm is to build a Secton operation between arguments and tools. The result of Section operation consists of vertices and edges. The result of Section operation contains:

  1. new vertices that are subjects of V/V, E/E, E/F, F/F interferences
  2. vertices that are subjects of V/E, V/F interferences
  3. new edges that are subjects of F/F interferences
  4. edges that are Common Blocks

◆ Approximation()

void BRepAlgoAPI_Section::Approximation ( const Standard_Boolean  B)

◆ Build()

virtual void BRepAlgoAPI_Section::Build ( )
overridevirtual

Performs the algorithm Filling interference Data Structure (if it is necessary) Building the result of the operation.

Reimplemented from BRepAlgoAPI_BooleanOperation.

◆ ComputePCurveOn1()

void BRepAlgoAPI_Section::ComputePCurveOn1 ( const Standard_Boolean  B)

Indicates whether the P-Curve should be (or not) performed on the argument. By default, no parametric 2D curve (pcurve) is defined for the edges of the result. If ComputePCurve1 equals true, further computations performed to attach an P-Curve in the parametric space of the argument to the constructed edges. Obsolete.

◆ ComputePCurveOn2()

void BRepAlgoAPI_Section::ComputePCurveOn2 ( const Standard_Boolean  B)

Indicates whether the P-Curve should be (or not) performed on the tool. By default, no parametric 2D curve (pcurve) is defined for the edges of the result. If ComputePCurve1 equals true, further computations performed to attach an P-Curve in the parametric space of the tool to the constructed edges. Obsolete.

◆ HasAncestorFaceOn1()

Standard_Boolean BRepAlgoAPI_Section::HasAncestorFaceOn1 ( const TopoDS_Shape E,
TopoDS_Shape F 
) const

get the face of the first part giving section edge <E>. Returns True on the 3 following conditions : 1/ <E> is an edge returned by the Shape() metwod. 2/ First part of section performed is a shape. 3/ <E> is built on a intersection curve (i.e <E> is not the result of common edges) When False, F remains untouched. Obsolete

◆ HasAncestorFaceOn2()

Standard_Boolean BRepAlgoAPI_Section::HasAncestorFaceOn2 ( const TopoDS_Shape E,
TopoDS_Shape F 
) const

Identifies the ancestor faces of the intersection edge E resulting from the last computation performed in this framework, that is, the faces of the two original shapes on which the edge E lies:

  • HasAncestorFaceOn1 gives the ancestor face in the first shape, and
  • HasAncestorFaceOn2 gives the ancestor face in the second shape. These functions return true if an ancestor face F is found, or false if not. An ancestor face is identifiable for the edge E if the following conditions are satisfied:
  • the first part on which this algorithm performed its last computation is a shape, that is, it was not given as a surface or a plane at the time of construction of this algorithm or at a later time by the Init1 function,
  • E is one of the elementary edges built by the last computation of this section algorithm. To use these functions properly, you have to test the returned Boolean value before using the ancestor face: F is significant only if the returned Boolean value equals true. Obsolete
