Exported dxf/dwg is rotated

I'm trying to export a slddrw to dxf or dwg (both have exhibited the problem).  They export fine, but when imported into AutoCAD, the portrait drawing is imported as landscape.  Does anybody know a SW option (or an AutoCAD one, I'm not picky) that controls this?  Any other ways of getting around this?

Thanks,

Karl
