overlap(?) objects in draw

curiously wondering why you deleted the message to which I was
replying???;
          to make what point???

       The initial messager was interested in knowing how to create a 3D
drawing of interlocking tubes;
          that can be easily be done by hand; even if it's done to
architectural scale.
