Hi,
I have seen one but I cannot remember where! I know that doesn't help but I can give some advice that will.
I am only a few months ahead of you in my Fusion Journey and was very raw when I started. I did know AutoCAD
but not much about Fusion. I ended up doing the Fusion Documentation Tutorials and several AutoDesk YouTube
Channel Tutorials which helped a great deal.
Also, one of the Gurus on this site is @TheCADWhisperer who also has a very good YouTube site with lots of Tutorials.
Between them that will get you started. Making heaps of mistakes and practicing will keep you learning. After that
pick Tutorials that interest you and give them a try.
Main thing to know is that the people here are great (and patient), but if you ask questions it is good to use both
Screen Shots and pictures (like you already have) but also put your attempt in Fusion as an attachment to your
Post.
To generate the File in Fusion click File then Export; save the file locally then attach it to the Post.

Cheers
Andrew
