I was able to download Autodesk’s Meshmixer which is compatible with 123DCatch and repairing 3D scans before printing. I think you can also draw from scratch if desired. Theoretically I could repair the scans of myself but note that my face really isn’t that clear. It is interesting to note that the texture of my jeans and shirt was captured. We need to find a better way to scan people – quicker with less time making repairs and more accurate features.
