I have been using Fusion for over 3 years now, got my own account so I can be independent of shop's account.
For the money, it's still a killer deal if you consider modeling and CAM features in one package, but.......... being that it is beta version sold as fully functional software, it's not completely honest and fair deal from Autodesk.
It is highly unstable, has numerous bugs that are being worked on, monthly updates do more harm then good to anyone running a business and I attribute that to constant change in bugs fixing that seems to fix one and introduce another.
For what it's worth, all CAM systems that I have used in the past, lathe work is always last to receive any attention,....... because "lathe work is easy" stigma.
I use Fusion to do all my milling on mill-turns and lathe section of it comes handy to visualize complete work in simulation.
Often times I use Mastercam for turning because it is far ahead of Fusion in terms of accuracy and dependability.
One thing I like about Fusion is ability to peck in long hand code for roughing or turn at alternate angle that benefits using stock as structural strength that benefits process.
Fusion is many things to many people so each part of it receives trivial approval depending on its effectiveness among users.
In recent survey request asking if I would recommend Fusion to a friend I gave it score of 7 on list from 1 -10, main reason being instability and lock of refinement.
"We are working on it" is not quite the right answer here, manufacturing is dependent on stable and predictable variables, one of which is software used to program daily activities.
So, I am dedicated user of Fusion but I also have other options at my disposal that compensate for lock of it's refinement.
I am near retirement and shop I work for has a lot of loose ends so I pick my own route to the finish line in most cases but I see some encouraging progress in functionality of Fusion since my first introduction to it, I wouldn't dismiss it on bases of lathe imperfections alone.
