    HI !
    mayby someone can help me. i want to read out the points in a Tpointselection tag. but have no idea how to do that.
    main(doc,op)
    {
         var tag = op->GetFirstTag();
         tag = tag->GetNext();
         tag = tag->GetNext();
         tag = tag->GetNext();
         var Type = tag->GetType();
         println(Type); // 5674 -> Tpointselection
         var name = tag->GetName();
         println(name); // "MySel1"
    }
    Any idea how to move on? Where are the points in the selectionTag?
    Thx!

    First, I would never depend upon a tag being in a particular place within the object's tag list. Do this:

    for (tag = op->GetFirstTag(); tag; tag = tag->GetNext())
    {
    if (instanceof(tag, Tpointselection))
    {
    var select = ((PointSelectionTag* )tag)->GetSelection();
    ...
    }
    }

    select is a BaseSelect class which contains an array which is the size of the number of points of the object. The points covered by the PointSelectionTag will be IsSelected(), the others not - think of this as an array of 1's and 0's. The selected points are 1, the others are 0. That is how a BaseSelect works, basically (same for PolygonSelectionTags as well). You can get the number of selected points in the array with select->GetCount().
