<p>Le script des objets de maillage Netgen était essayé ici : <a rel="nofollow" class="external free" href="http://forum.freecadweb.org/viewtopic.php?f=18&t=16944#p134519">http://forum.freecadweb.org/viewtopic.php?f=18&t=16944#p134519</a>, mais a quelques limitations . Au contraire le script d'objet de maillage GMSH supporte complètement le script python.
