Draft OCA
Description
Draft OCA is a software module used by the 
Std Open, 
Std Import and 
Std Export commands to handle the OCA file format.
The OCA file format is a community effort to create a free, simple and open CAD file format. OCA is largely based on the GCAD file format generated from gCAD3D. Both formats can be imported in FreeCAD, and the OCA files exported by FreeCAD can be opened in gCAD3D.
Apertura
Esta función importa archivos OCA/GCAD. El formato de archivo OCA es un esfuerzo de la comunidad de crear un formato de archivo de abierto, simple y libre. OCA está basado en el formato de archivo GCAD generado por gCAD3D. Ambos formatos se pueden importan en FreeCAD, y los archivos OCA exportados por FreeCAD se pueden abrir en gCAD3D.
De momento se importan los siguientes objetos de OCA:
- Líneas
- Arcos y Circunferencias
- Áreas cerradas
Exportación
Los objetos que se pueden exportar de momento son:
- Líneas y wires (polilíneas)
- Arcos y circunferecias
- Caras
The following FreeCAD objects can be exported:
- Lines and wires (polylines)
- Arcs and circles
- Faces
Preferencias
Los siguientes parámetros se pueden especificar en la pestaña de Preferencias (menú Editar -> Preferencias -> Croquis):
- Importar áreas cerradas o no
See Import Export Preferences.
Scripting
See also: Autogenerated API documentation and FreeCAD Scripting Basics.
To export objects to OCA use the export method of the importOCA module.
importOCA.export(exportList, filename)
- For the Windows OS: use a / (forward slash) as the path separator in
filename.
Example:
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")
