Short description of error
Blender doesn't import fbx file

Exact steps for others to reproduce the error
Try to import the attached fbx file. Blender shows this error message:

The file was produced in AutoCAD, exported to fbx and converted to fbx 2013 (a.k.a. 7.0 that Blender supports) using FBX converter 2013.3

Ok, so same cause as for your collada report - vcol data in that FBX file is truncated somehow… We could add a bunch of checking code in FBX importer to protect us against such case, but this would be very verbose, and to just avoid a mere python exception in invalid file case, not worth it imho.

So thanks for the report, but considering there is no bug here, we simply cannot handle nicely all possible case of data corruption.

No data corruption. File imports OK in Autocad 2015, 2014, maya and 3ds, and is copy verbatim of the original file base (AutoCAD ACIS solids), i just send a tiny little part of the file, and just checked the geometry is OK.

But dealing with propietary formats is always hard, so i have to agree with you in that you can't handle all corner cases propietary code and formats do all the time.

Thanks for your time, and happy new year.
