Totally understand. If @72Pony or I were to help tweak a file, we would show you our work so that you could understand what was happening.
I totally get that if we supplied a file back that worked, there would be little learning value in that. Also, if you have a very specific task/technique you are looking to learn, post it on this thread:
@TinWhisperer is a resident expert/hero on all things Fusion 360 and beyond. He has many videos on YouTube and Twitch that he might direct you to or if it is a topic that has other interests, he will post a video doing the exact problem/solution you are looking for.
I went through the same mental gymnastics when I first started. So much information coming from so many different directions. Good luck and happy hunting.
