You say you have a cad cutter, so I would assume you have cad as well? If so, maybe it will let you import the file (at least Autocad does). Then you can scale the image to a known length, preferably a large part of the car since that will increase your accuracy. From there you can draw your ideas on it. I do this a lot.
