For those who like to RTFM, here's the official Autodesk University 2011 123D Catch manual!
It may be a little outdated, but it was invaluable at the Met MakerBot Art Hackathon!
The license should probably be ©2011 Autodesk, Inc. All rights reserved, but that doesn't exist here, so it's shared with the closest license to ARR.
