Physical to digital process. 1. I first built an armature from the final intent sketch. 2. I then used automotive clay to sculpt over the 3D printed armature. 3. Once happy with the clay model I had it digitally scanned and re-meshed for CAD handling. 4. From the scanned data I could then build my CAD surface model. 5. Finally, I 3D printed and finished my snow shoe frame.
