Re: examples of complex TNode collections?

Thanks Mike.  I think what I'm trying to do is a bit different
than that.  I'll try to illustrate it using your example...

Your example placed two shapes at the origin, but I'd like to
place them in a particular orientation relative to each other to
build up a sub-detector, say like this:

     _________  ____
    | Big     ||sml |
    |         ||____|
    |         |
    |         |
    |_________|


Then I want to take several things that are a combination of Big
and sml and arrange them to build up my detector, say like this:

 ____  _________       _________  ____
| lms||     giB |     | Big     ||sml |
|____||         |     |         ||____|
      |         |     |         |
      |         |     |         |
      |_________|     |_________|

       _________       _________
      |         |     |         |
      |         |     |         |
 ____ |         |     |         | ____
| lms||     giB |     | Big     ||sml |
|____||_________|     |_________||____|


The actual geometry is more complex than this sketch, so I don't
want to place each individual shape many times.  Instead I'd like
to build the sub-detector combination once and place it many
times.  But I haven't been able to see how I can add a node to a
parent node's list, but in different positions.  Is this
possible?  Maybe not and each shape has to be positioned
separately each time, but I suspect/hope that it is just that I'm
not seeing how to work with node lists effectively.
