Some fun for a Friday afternoon. Check out what the the Autodesk Inventor team is doing with the Inventor Publisher product and its accompanying mobile viewer. Once the cool factor of "wow, Lego instructions on the iPad" wore off (I mean, c'mon, I survived my youth with paper instructions - or no instructions at all!) I started thinking of other applications of this technology. I posted last year about some early work in the "mobile Revit" arena from third party developers. The comments back then seemed to indicate an interest (if not a full-fledged need) for mobile access to views from a Revit model. Instead of trying to view an entire BIM in a mobile device, could you see using a tool like this to view, communicate, and verify shop drawings (shop models?) for on-site installation?
