Save as ACAD Dwg - Anyway to eliminate Line Thickness Settings?

Hello,

I am creating drawings for a client and saving them as DWG files. The client uses ACAD and woulld like the lines in the drawings to appear without thickness (as the use the color settings in their plot file to deal with this). The drawings I sent them pull up with a thickness assigned (and very visible) to the lines. Is there a way around this (without exploding things in the Autocad file)?

Thank you!
