Save 2D drawing as a Vector PDF instead of Raster?

The graphic design department would like to use our regularly saved PDFs for their visuals. Problem is, they all seem to be saved in a raster format, where a vector format is preferable. Is there any way to change the standard save format to vector? I would rather kill two birds with one stone and not have to save as both PDFs and DXFs.

Thanks.
