I have installed import_off addon from this github repo. This addon provide import functionality of the ".off" file in blender using the GUI. But there is no way I can import ".off" file using python.

Please tell if there is any way I can import .off files using python, since I intend to work on many 3D models and using GUI is not possible on all of them.


You are under a misapprehension that you can not use the import OFF addon you posted.

Get the name of the operator by mousing over the import menu bpy.ops.import_mesh.off(...)

Typing the operator in the python console and using autocomplete CrtlSpace exposes the parameters (Same as those in the UI).

bpy.ops.import_mesh.off(filepath="", filter_glob="*.off", axis_forward='Y', axis_up='Z')
>>> bpy.ops.import_mesh.off(

Simply pass the filepath of an OFF file to the operator in your own code.

Eg: to import with default settings.

filepath = "some/path/to/file.off"

This can be done for pretty much all import / export addons.

  • $\begingroup$ To define a 3d space used by an application, need which axis is up, for blender z, and which axis points towards you (y) in front ortho. A lot of other applications use y up. Without converting a blender model will be exported with the wrong alignment. $\endgroup$ – batFINGER Dec 2 '16 at 2:30

Answer from @batFINGER worked for me, but I had to pass the parameters as named parameters.

Do it like this:

bpy.ops.import_mesh.off(filepath = filepath)

Not like this:
