This is what autodesk calls progress. 🙂 They feel we were overwhelmed with all the pull down menus, so they decided to remove them. Would have been nice if they would have given a road map to the new locations. But then again they need something to put in the next upgrade, otherwise you don't feel like your getting your money's worth for the subscription. You can still get back to the old style pulldowns if you prefer. Whether or not they have the new commands available in them is still a question. Under the WINDOW pulldown menu go to PULLDOWNS and select whichever menu type you prefer. Be careful though, if you set one up, then decide to try another all your previous settings will be lost. I believe most of us have discovered this one the hard way.
Good luck.
