Draft

Descrizione

Draft OCA è un modulo software utilizzato dai comandi Std Open, Std Import and Std Export per gestire il formato OCA.

Il formato di file OCA è uno sforzo della comunità per creare un formato di file CAD gratuito, semplice e aperto. OCA è in gran parte basato sul formato di file GCAD generato da gCAD3D. Entrambi i formati possono essere importati in FreeCAD e i file OCA esportati da FreeCAD possono essere aperti in gCAD3D.

Importazione

Si posssono importare i seguenti oggetti OCA:

• Linee
• Archi e circonferenze
• Aree chiuse

Esportazione

È possibile esportare i seguenti oggetti FreeCAD:

• Linee e spezzate (polilinee)
• Archi e circonferenze
• Facce

Preferenze

Per ulteriori informazioni, consultare: Preferenze di Importa/Esporta.

Scripting

Script

Vedere anche: Draft API e Nozioni di base sugli script di FreeCAD.

Si possono esportare elementi in Oca usando la seguente funzione:

importOCA.export(exportList, filename)

• For the Windows OS: use a / (forward slash) as the path separator in filename.

Esempio:

import FreeCAD as App
import Draft
import importOCA

doc = App.newDocument()

polygon1 = Draft.make_polygon(3, radius=500)
polygon2 = Draft.make_polygon(5, radius=1500)

doc.recompute()

objects = [polygon1, polygon2]
importOCA.export(objects, "/home/user/Pictures/myfile.oca")
