What nonsense. The file I got was correctly exported from FreeCAD no matter
what you believe; maybe the later versions or nightly builds are better,
but that
has nothing whatsoever to do with the purpose of this exercise.

 If you want to compare results, you can convert some models from here:

http://www.steptools.com/support/stdev_docs/stpfiles/ap203/

The weldment and nasty_cheese files should be enough. Also remember this
is not a competition; OCE is being used to provide built-in support for
viewing STEP and IGES models but if people want to install FreeCAD that
is their business. In the future installing FreeCAD will never be a
requirement
of kicad to view files and even the installation of OCE will only ever be
optional. The only purpose of comparing output is to ensure that we get
similar results.

In addition here is an IGES file with color to convert:

You may also want to convert tork.stp to see if you get the expected model;
my conversion is missing some surfaces.
