123D Catch got stuck

Autodesk’s 123D Catch ist a great simple tool for 3D scanning objects with your phone. With the app you’re simply taking some pictures of the object. It uploads them into the cloud. And some minutes / hours later you’ll get a 3D model of the object for 3D printing and remix.

If everything works. Otherwise it will display “Thinking some more” forever.


That happened to me this weekend. But i needed the model for a remix for an exhibition. Thus i had to get the photos from the app. That wasn’t that obvious because 123D App stores the photos in Android’s internal storage.

There’s a way to get them without rooting the phone:

Just create a backup of the App (com.autodesk.Catch) via Titanium Backup or Android Developer Tools:

adb backup -apk com.autodesk.Catch

You’ll get a file named backup.ab. There are several ways to unpack it. I simply used Android Backup Extractor: and extracted the .tar via right clicking it and Archive Utility in OS X finder.

java -jar abe.jar unpack backup.ab backup.tar

Finally there were my images from the capture. I’ll now try different photogrammetry tools for the reconstruction.
