Firstly, I've been waiting for this for a long time (since the inventorfusion.com was first available) and while initially a little lost (like others i thought it would be a direct addon) the scope for the future looks really exciting, especially with the DWG file type. As for the naming convention, does it really matter (when you think about it, fusing Inventor with AutoCAD king of gives the name away). Also my 11 year old sons really like it, spending an hour or so playing with it Sunday afternoon and coming up with some interesting shapes (though not the Death Star/Battle Cruiser they were hoping for)
It would be nice to have some exercises in the Getting Started to make sure we get acquainted with all the aspects of the UI, as some things (like how to do a Through All Hole). Perhaps a CHM could be added soon???
