Blender 2.55 and Python 3ds file import

Hi everybody,
I’m new in forum and also in Blender.
I use Blender 2.55 and Python 3.
I need to import a 3ds file into Blender (2.55) through a Python (3) script.
I found the function
bpy.ops.import_scene.autodesk_3ds(…)
documented at blender doc site.
But it doesn’t work: it gives me an ENUM error.

Is there someone that has already use this import function?

Thanks all in advance

Did you try to do it by menu item ?

File -> Import -> 3D Studio

This operator call File Browser.

I sugggest you to look how was made import_3ds.py file in 2.55/scripts/op/io_scene_3ds folder.

Hi zeauro, thank you for your reply.

Ok: now I can import the 3ds file (I don’t know why in the past I cannot import, but anyway …).
I have another problem: the scene that I have imported is too big, very big, compared with the plan. I have tried to use the parameter constrain_size, but with no effect.
Also with import menu in the GUI the effect is the same.

Can you help me?

Thanks
