I was in the same boat. So I started to look at the older version of fusion and cross referenced the new version and wrote down where it was and what it was now called. It's all still there. But it's been moved and or renamed. But rest assured it makes very little sense when you start as it's not using usual windows logic. I found ignoring sketches. When I started helped me to alter basic shapes to get what I wanted. Now I need to learn how to apply a sketch to use as a tool to cut or alter the shapes I can create. I am aware you should start using sketches but just could not get my head round it.
