Autodesk Impression is very good at making a cad drawing look hand drawn. Impression is a free download for subscribers, I am not sure of the cost if you are not a subscriber. Impression allows the user to render the drawing in different mediums--colored pencil, watercolor, or markers. The software has a couple of tutorials that teach the basics. -------------------------------------------
