Hello,

After using a create designer such as ClosedPolyLineVObjectCreateDesigner or LineVObjectCreate desginer, I am attempting to keep a reference to the newly created Vector Object.

this is what I am trying now, but the "old designer" doesnt contain a VObect... where did it go?

Code:
if (e.OldDesigner.GetType() ==
    typeof(ClosedPolyLineVObjectCreateDesigner))
{
    regionList.SelectedNode.OutlineVObject =
        (PolylineVObject)e.OldDesigner.VObjects[0];
}

However I get an index out of range error, there are no obects in e.OldDesigner.VObjects, where did my newly created VObject go?

Hello,

I recommend you to handle MultiLayerViewer.LayerChanged event and track type of the changes. Something like that:

Code:
void _mlv_LayerChanged(object sender,
    Aurigma.GraphicsMill.WinControls.LayerChangedEventArgs e)
{
    if (e.ChangeType ==
        Aurigma.GraphicsMill.WinControls.LayerChangeType.ObjectAdded)
    {
        Aurigma.GraphicsMill.WinControls.PolylineVObject pl =
           e.VObject as Aurigma.GraphicsMill.WinControls.PolylineVObject;
        if (pl != null)
        {
            //do something with all newly added polylines
        }				
    }
}
