I installed Orthogonal Toolbox.
And I cannot find export neither in it nor in VEA.
But even if I miss it in VEA, it still make sense to concentrate similar functions in one place.

But now, or yesterday, I would like to know how to export? rules as text

Thanks, Scot,
you do a great job and it really a big help to save a lot of time.

Sure, I saw Database|Report functionality but it is not of any help in order to go between text rules and source model.

For ex., I would like to export rules from sample models, edit them and import back.
Or I would like to elaborate all big model in simple terms and through rules without using complicated constraints. So, either I do not use graphic specifications to add elements or I just should repeat the work in file with text rules?

So, as I understood your import rules functionality implies that I should create any model rules in form of text from scratch. I can't also share it. If I make changes graphically 
Or I miss something?

I understand that it does not support complicated things but it impedes reuse of model in form of working directly with rules in text file.

Anyway, can you share your (enormous) experience, advise how do you work with models?

3d case:
"new model" is just the same model but after adding elements "graphically"... well, through VEA.
After that I should update the text file  with rules or it doesn't serve me for anything else then first shoot to start
But imagine that I want to wrk at some branching versions of the same model iteratively and still use/have  text rules (around)
Might be I have wrong plans due to lack of tools knowledge

thanx a lot, Scot,
you save the ORM cause in Portugal answering my silly questions!
