Install Inkscape, it's freeware and easy to create DXF files. Open the image up in Inkscape, then select it in Inkscape. Then, go to Path -> trace bitmap, then select edge smoothing or something like that. Click ok then go close the window. Drag the original image away and then delete it. The remaining image should be an outline. Save the final product as a DXF file and then open it up in your CAD program.
