This may be old news to some, but AutoDesk has a free service called ReCap360 where you upload pictures and it generates a 3D model. I will toy with this in the future to see how it works, but it looks very good. The detail of the 3D model produced at 1:50 in the video below is remarkable. You can import the 3D model in your CAM software to generate code to make copies.
