So, wherever you see splitWay() that's where the "copying" occurs.
Maybe it is too late in the evening for me to understand the problem. In the splitWay() the line is splitted. Yes, a new list<Coord> is generated. But the points inside it are moved from one list to another. There is no new Coord(). So a CoordNode stays a CoordNode.
Yes, it would stay a CoordNode if it was a CoordNode at the time the line was split. But, Coord->CoordNode transformation happens after all the splitting has occurred. So at the time the lines are split, all Coords are Coords! Cheers, Mark
