Fusion360 is an amazingly powerful program and to have it available free is equally amazing. I've had it for a couple of years and it does expire for hobbyists, but all one has to do is renew! It's even free for lower gross income small businesses, which is again an amazing attribute for such a capable piece of software. Many users advance from 3D printing to CNC routing and machining and the program generates tool paths and g-code too, still at no cost. Did I mention I'm amazed?
