Before Using AutoCAD, I use a product called Autosketch. When I switched to AutoCAD was difficult to figure out how to use the software. A few months and a good reference book helped out and I became reasonably proficient. The same happened when I switched to SolidWorks. Some things were just not logical and I couldn't make things work the way I wanted. I bought some books called "SolidWorks Bible" by Matt Lombard (one with each version upgrade) which helped me through.
I am still working with SolidWorks after some fourteen years and it is second nature to me now. Parts can be whipped out in a few minutes and full assemblies in a hour or so. I use it do do sketches rather than pencil and paper. I have Fusion 360 installed as well and dabble with it occasionally. It is as confusing, as the others were. I don't use it because I have SolidWorkjs and it is the easiest path for me. For me to become proficient in Fusion will require some total immersion tome, probably a couple of weeks, at least.
So why do I have Fusion at all? It is because they offer a seamless migration to the CAM programming for my CNC. AutoDesk's recent philosophy to permit free non-commercial use of the software is IMO a huge plus. I have a licensed seat of 2012 SolidWorks that cost me around $4K but a "subscription" which would give me current versions and access to technical help would cost me around $1500/ yr. With Fusion, they upgrade continuously, and every time you log in, you receive the latest update. They now have an electronic CAD package with which can create schematics and printed circuit boards and convert them to solid models that can be used to mill a circuit board.
Fusion's model renditions are also much nicer than SolidWorks, at least if you are using the standard version. Some of them rival a photographic image. I suspect that there are other features that I am unaware of as well.
I would recommend that a new user stick with it. It will be frustrating at first but eventually it will work out for you. There are hard copy reference books on Fusion 360 available on Amazon, also a Kindle book, free for 30 days. Amazon has Kindle reader apps for various platforms. John Saunders at NYC CNC has done quite a few You Tube videos on Fusion. They are not as complete as I would like to see them but they are a useful tool. I would recommend starting with simple objects at first. The tutorials tend to try to cover too much and, doing so, they often get confusing.
