importing CAD using model builder

I am trying to mass import some cad floorplans. My model runs fine if I specify just 1 specific CAD file. I just can't figure out the iteration portion. I've tried using iterate files and iterate datasets. I only need polys and anno, ultimately. I attached a screen shot if it helps. I'm clearly missing some key part of this. HELP! Doing this manually is not even an option.
