Cannot save to dwg

I cannot get this file to save to dwg format.  I've tried to save as, export, convert it to dgngraphics then save as, export.  I've tried to downgrade the civil model to nothing, that crapped out as well.  Any one got a clue how I'm supposed to do this.  This file is literally just a survey dump from a csv and converting to use civil 3d for design.

Thanks
