Macro Geodesic Dome/fr

Description
Cette macro crée la coque d'un dôme géodésique paramétrique. Le rayon du dôme et les paramètres de fréquence sont définis au moment de la création.



Utilisation
1. Installez la macro en utilisant le gestionnaire (menu Outils → Addon Manager). Sur l'onglet "Macros", sélectionnez "GeodesicDome", cliquez sur "Installer". Fermez ensuite Addon Manager.

2. Exécutez GeodesicDome.FCMacro. Une fenêtre de dialogue devrait apparaître

3. Spécifiez les paramètres et cliquez sur.

La forme d'un dôme devrait apparaître. Vous pouvez ensuite modifier les paramètres du dôme en modifiant les propriétés de l'objet GeoDome.
