Re: [CAD_CAM_EDM_DRO] Re: poor mans digitizing gizmo

Actually, you only need one camera. Take the picture, turn the item (or
move the camera) and take another picture. The more pictures the
better. Then you use photogrammetry software to create your 3D model.
Uzr3d for the Mac and PC is one such package.
