Hi Al, STEP is something that I would like to add in for version 2.0 .

I haven't figured out yet if it will be built in or some kind of add-on. There are a couple of other things other than just licensing cost that can factor into that, like if it increases download size by very much.

But most likely it will just be built in directly to v2.

I have added this to the Wiki wishlist page: http://moi3d.com/wiki/Wishlist so I can keep track of it better.
