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

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")
