Macro Unfold Box/it

Descrizione
Questa macro permette di creare lo sviluppo delle superfici di un solido con facce piane, di disegnare le facce in una pagina, e di inserire il disegno in un foglio A3 o A4.



Installazione
Secondo quanto descritto in Macro for unfolding box surfaces

Copiare il file del codice nella directory: Aggiungere i modelli del foglio : A3_Landscape_Empty.svg A3_Landscape.svg  A4_Landscape_Empty.svg  A4_Landscape.svg
 * Linux & Mac  : $home/.Freecad/Mod/unfoldBox.
 * Windows : C:\Program Files\FreeCAD0.13

Opzioni

 * Scala manuale o automatica
 * Formato della pagina: A3, A4
 * Tabella (secondo i modelli di FreeCAD)
 * Raggruppamento dei disegni nella stessa pagina se è possibile.
 * Unire le facce su un lato.

Utilizzo

 * 1) Selezionare un oggetto creato con Part, ad es. un oggetto creato con Loft.
 * 2) Scomporre l'oggetto (utilizzare Draft -> Retrocedere)
 * 3) Selezionare le supefici
 * 4) Eseguire la macro
