I'd like to make best use of ORM Designer now that I have a license, but I haven't been able to find any "help" files in ORM Designer that explains what a regions is nor used for. I also didn't find any info on a "region" in the support forum.
regions serve only for better visual organisation of your model. You can find more information on our documentation here: http://help.orm-designer.com/en/model-basics
Anyway, thank you for info that you weren't able to find this documentation. It's a good feedback for us that we need to make it more visible!
