I've checked out the What's New on the Large Scale Design stuff. It is interesting, but would it be possible for product designers to get some context for this? Should we be thinking of the Dedini images of a chemical processing plant, or is there some other way this might have been intended to have been used? The Grid looks pretty specific to some sort of structural framework, but the IFC file type could have used a sample file to at least demonstrate what it does. Can anyone offer a little more context for these tools?
