I am a daily Solidworks user and have given Fusion a decent test run of what I would use it for. I find the interface of Fusion to be very clunky compared with Solidworks. I know that I am more familiar with Solidworks and I am taking that into consideration.
By far the biggest weakness for me with Fusion is the lack of thorough parametric control. Correct me if I am wrong but once you make an extrusion there isn’t a way to change the features of that extrusion other than length with push/pull. In addition to that, the number of ways in which a feature can be created is limited when compared to SW.
Having said that I do think Fusion is very good for being free. The CAM portion is top notch! I have set up tool paths for 2 sided milling on an Xcarve. So many settings for more complicated milling that I didn’t even touch. Its thorough but easy to understand with all of the little built-in help videos.
My 2 cents.
