The OCA file format is 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
For more information see: Import Export Preferences.
You can export elements to OCA by using the following function:
import FreeCAD, Draft, importOCA p1 = FreeCAD.Vector(0, 0, 0) p2 = FreeCAD.Vector(1000, 1000, 0) p3 = FreeCAD.Vector(2200, 1500, 0) p4 = FreeCAD.Vector(2500, -100, 0) obj1 = Draft.makeWire([p1, p2, p3, p4]) obj2 = Draft.makeWire([p1, -2.3*p2, -0.8*p3, -1.8*p4]) objects = [obj1, obj2] importOCA.export(objects, "/home/user/Pictures/myfile.oca")
