Descrizione
Questa macro crea il guscio di una cupola (sfera) geodetica parametrica. Il raggio della cupola e il parametro di frequenza (fattore d'arco) sono definiti al momento della creazione.

Utilizzo
1. Installare la macro usando Addon Manager (menu Strumenti → Addon Manager). Nella scheda "Macro", selezionare "GeodesicDome", fare clic su "Installa". Quindi chiudere Addon manager.
2. Avviare GeodesicDome.FCMacro. Dovrebbe apparire una finestra di dialogo
3. Specificare i parametri, e poi fare clic su OK.
dovrebbe apparire una forma a cupola. È quindi possibile modificare i parametri della cupola modificando le proprietà dell'oggetto GeoDome.
Script
(questa è una vecchia versione non parametrica dello script. La versione aggiornata è nel repository delle macros di FreeCAD, qui! )
