I use Visio for Enterprise Architects to create logical models (sets of related tables) from ORM source models. this works very well, except that for some projects when I reorder the columns in the logical model tables --which I am supposed to be able to do -- the order gets reset when I make changes to the ORM and rebuild the logical model. This only happens with some of my projects and I can't figure out what it is about those projects that leads to this behavior.
