0026174: Data Exchange, IGES - Loss of color after the second write of file

Browse Source 
A copy of myface is made, where further on the copy the geometry changes. We connect the face, wire, edge of the original shape with the one whose geometry was changed. This is done in order to get the original shape in the TransferWire() and TransferEdge() methods.
