right on. I was about to make that point. I personally use 5 different CAD packages. Learning the basic concepts of CAD design in the first one made learning the other 4 simple. Don’t forget that Inventor is not going away. importing an inventor model into f360 is pretty seamless. creating machining toolpaths or 3d printing is a different topic and parts of f360.
Keep in mind unless a F360 expert steps up (and I hope one does) to teach a class it’s inventor, learn f360 on your own, or nothing.
