Описание

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.

Importing

The following OCA objects can be imported:

Lines
Arcs and Circles
Closed areas

Exporting

The following FreeCAD objects can be exported:

Lines and wires (polylines)
Arcs and circles
Faces

Preferences

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.

Пример:

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")
