I have just uploaded some revised documentation to the CamBam website which contains an updated tutorial on the 3D machining operations.
CamBam 0.9.8 documentation - 3D Profile
This is similar to the 3D tutorial currently available in the offline documentation (available from Help - Contents), but has has a revised section on moving and orienting the 3D objects.
This documentation will be part of the next CamBam release (0.9.8K) and will replace the main documentation when 'K' becomes the latest stable release.
