Pour avoir des entit\u00e9s ligne, il nous faut un troisi\u00e8me champ indispensable qui contienne un identifiant de ligne: tous les points d&rsquo;une ligne auront la m\u00eame valeur pour ce champ. Un quatri\u00e8me champ est n\u00e9cessaire pour indiquer l&rsquo;ordre des points. mais ce champ nous verrons comment le cr\u00e9er au moment d&rsquo;utiliser l&rsquo;outil de
