Hey everyone, if you've gotten the newest Fusion update, as of late January 2026, you'll not a new workflow when creating a new document. They've introduced "Intent Driven Design". Which option you select "Part Design, Assembly Design, Hybrid Design, etc" will modify the UI (making it NOT line up with some of the early lessons that we have).
I'll be working on updated lessons to keep up, but in the meantime, if you select "Hybrid Design" you'll be setup with the closest option to how it used to work (and how our lessons show the UI).
Here's more info on the change, from Autodesk
