Detailed Description

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 connected 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;
