Summary

0026123: BRepOffsetAPI_ThruSections history is wrong.

Description

Code snippet to demo the issue:
Load the model attached as loftWires.brep and find the three wires to make loft as below:

BRepOffsetAPI_ThruSections aLoft(Standard_False, Standard_True);
aLoft.AddWire(aWire1);
aLoft.AddWire(aWire2);
aLoft.AddWire(aWire2);
aLoft.Build();

//aEdge1 is the first edge of aWire1.
aLoft.GeneratedFace(aEdge1) is empty.

Another issue is that, if the first shape is a vertex, how to get the vertex history? It seems need to revise the history for BRepOffsetAPI_ThruSections to support vertex history.

Notes
(0040120) Vico Liang (developer) 2015-04-22 17:36	The cause might be that the original wire edges are splitted during the model operation so the edge can't be found in the history.
