Full Version: Free 3DM importer add-on for Blender

Hi,

I just saw this discussion at the Blender Artists forum, about a free add-on that can import Rhinoceros 3DM files.

https://blenderartists.org/t/import-rhinoceros-3d-files-into-blender/1136070

I'm not sure if it's also fully compatible with MoI 3DM files, but it's definitely interesting.

Regards,

Metin

Hi Metin, it does not appear to be compatible with 3DM files saved from MoI because it only processes display mesh information that Rhino caches in 3DM files and does not read NURBS data directly.

Hi Michael,

That's a bummer. I've mentioned MoI in the discussion. Hopefully the creator can add MoI 3DM compatibility.

It is not more easy to load the 3D Rhino file inside Moi then export as OBJ ?

And the file OBJ will be surelly better than the transformation by the future Blender Plugin! :)

MoI's mesher is the best, yes. But a dynamic bridge between MoI and Blender would be very nice.

Hi Michael,

Here's a response from the Blender 3DM add-on developer:

"It currently needs indeed the render meshes (display mesh), but I’ll be using Rhino Compute in the (near-ish) future, so that importing a 3DM without render meshes in the file will use a (local) Rhino instance for the meshing. You could of course also request the Moi 3d developer to save the display meshes as well…"

Regards,

Metin

Hi Metin, that's great that he has already got a solution planned for that!

It doesn't really work for MoI to save display meshes in 3DM files because it greatly increases file sizes. There's also other problems as well, see here for some previous discussion:

What is "3DM without render meshes in the file will use a (local) Rhino instance for the meshing"
a tranform nurbs surfaces in a mesh ?

Hi Pilou, it sounds like it will use a locally installed Rhino to make the mesh, communicating with it from within the Blender plug-in. You'll probably get better results just exporting to .obj format out of MoI though rather than using the plug-in.

Got it. Well, it was almost good news. ;-)
