Aaron, look for a program that converts "RASTER TO VECTOR" that is the correct terminology. As someone pointed out bobcam I think may offer that feature, many others might do the same or better. I will attach a link that might help you. Some of this programs are free so dig in at your own pace. As for the threads, yes you can do them in a VMC as long as your cam software outputs the code or you can actually do it by had, there's nothing to it, really!!!
