Exporting to FBX or likewise

Anonymous · ‎07-28-2015

Hi, I'm looking for ways to export from AutoCAD 2015 for Mac to anything that keeps 2D and 3D as separate objects, preferably in the correct layers, to be used eventually by Unity 5. (For reference, it's a landscape reconstruction file including layers for different area states.)

As far as my search yielded results, both FBX and OBJ options are not available for export in AC for Mac'15, and neither can I use STL to export the 2D objects (only solids and watertight meshes would work). Are there any more options to try?

Thanks for any help.

Hi,

I have found this sentence:
"Unity can read .FBX, .dae (Collada), .3DS, .dxf and .obj files,"
here:
http://docs.unity3d.com/Manual/HOWTO-importObject.html

Have you tried save your drawing in DXF format which supports 2D and 3D, and than import it in Unity?

Hi Maxim,

I just found the same link and am trying a direct .dxf import right now. Will post any results, thanks.

I've tried importing a .dxf but it immediately crashed Unity. I'm now going to try a Maya route ...

DXF files have formats, much like DWG files. It's not a static file format.
Did you save or export to the lowest format DXF possible for your test? I would try it again.

Thanks, I did not know that, mainly because the program I used to generate the DXFs (Adobe Illustrator) did not offer any option for version choice.

The larger thing I was solving is to get a proper workflow from 2D vectors derived from old maps, done in an Illustrator file, into a format that joins it with 3D shapes derived from it, and then be able to export it into a format Unity can take in order to build an application around it. All on Mac. For the moment I found I can export to Illustrator 8 (a really old version) and open that in Maya, from where it can be exported as FBX.

The much better way I think (and I am pretty surprised it seems to be this much of a 'niche' in terms of solutions, for a project that perfectly falls within the professional boundaries of digital heritage applications) would be to get everything (2D, 3D) in AutoCad and be able to export straight from there. But not for Mac users, apparently...
