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.
The following OCA objects can be imported:
- Arcs and Circles
- Closed areas
The following FreeCAD objects can be exported:
- Lines and wires (polylines)
- Arcs and circles
To export objects to OCA use the
export method of the importOCA module.
- For the Windows OS: use a / (forward slash) as the path separator in
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")
