Here's a file, exported out of ZW3D.
I've tried several Inventor versions, beginning from 2010 and ending in 2015. 2010 to 2013 took very long, and I broke by Taskmanager. 2014 only showed a few lines, 2015 showed lots of garbage.
After that I tried IGS import to Rhino, without any problems. STEPout from there could be imported ok to Inventor.

This is how it opened in SolidWorks 2013.
It opened with quite a few errors - I tried to Heal All, but gave up after several minutes and killed the process.

Thanks, Michael and Jeffrey.
Nice to see, that my combo of Inventor and Rhino can end in no bad results. Ok, I did some cleanups.
