Anun,
Are you using the latest version of CAESAR II? What does the message file say?
Those errors usually mean there's something in your model that ISOGEN thinks is unbuildable, such as a 10" pipe connected directly to a 6" without a reducer - what is a valid situation for stress analysis isn't always valid for buildability.
If you'd like, send your model to techsupport@coade.com and reference this thread.
