DXF Export Problem

Hello!

I am trying to export a drawing to Illustrator so that i still have splines and circles. At some point this must have worked for me, as i have old exported DXF files which have splines in them. But with my current Drawing i cant get it to work, Solid Works will export all the Splines and Curves as edgy polylines! I already tried all the options and different DXF standards, but nothing helps...

Thanks for your advise!
