Have you tried to make a backup copy of those models and save them under a different name or in a different location? To me, that is the simplest. That way if the original model gets corrupted or damaged, you can just copy and paste or re-name your backup copy to where it needs to be.
Yes I do and that has worked many times. I guess that I am trying to streamline the process of documentation, while keeping the benefit of not having to rekey if there is a problem. It would be nice if Monarch had a automatic backup feature for projects and models that could be turned on and off by the user. Thanks for your suggestion.
