Data Structures

class BRepLib_MakeWire

Provides methods to build wires.

A wire may be built :

* From a single edge.

* From a wire and an edge.

A new wire is created with the edges of the
wire + the edge.
If the edge is not connnected to the wire the
flag NotDone is set and the method Wire will
raise an error.
The connection may be :

. Through an existing vertex. The edge is shared.

. Through a geometric coincidence of vertices.
The edge is copied and the vertices from the
edge are replaced by the vertices from the
wire.

. The new edge and the connection vertices are
kept by the algorithm.

* From 2, 3, 4 edges.
- A wire is created from the first edge, the
  following edges are added.
  
  * From many edges.
- The following syntax may be used :
  
  BRepLib_MakeWire MW;
  
  // for all the edges ...
  MW.Add(anEdge);
  
  TopoDS_Wire W = MW;
