Описание

Draft OCA is a software module used by the Std Open.svg Std Open, Std Import and Std Export commands to handle the OCA file format.

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.

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

For more information see: Import Export Preferences.

Scripting

See also: Draft API and FreeCAD Scripting Basics.

You can export elements to OCA by using the following function:

importOCA.export(exportList, filename)

Пример:

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")
