It’s definitely got a steep learning curve. I guess I got spoiled on the CAD side by picking up SketchUp fairly quickly, at least for basic things. That being said, once you get a handle on the basics in Fusion, it is extremely powerful and the CAM is exceptional. But Greg is correct, the investment is probably a few weeks of time to get even a basic foundation. And it’s a lot of head scratching and learning and re-learning. I’m finding if I don’t use it for a week I still regress quite a bit due to the steep curve. I’m kind of settling in to the idea that I probably need to commit a few hours a day to it for about two weeks to get a solid foundation that I don’t regress on.
So, if you just want to cut things you already have drawn in 2D, there are definitely quicker ways to get there. If you have more complex ideas and extremely high precision things in mind, climbing the Fusion mountain is probably the path.
