It's mostly in association with working with my CAM package. It likes IGES and STEP better than 3dm. So when I work with my brother, we go back and forth with these other formats... But it really isnt an issue for me. For the most part, I just go one way with the models, I was just engaging the dialogue. The loss of all the Pre-populated styles seemed a bit "out" with MoI's less-as-more target. The ability to re-populate a default list is just an addition I thought could be useful.

Hard to find anything you havnt been considering already :O
