@cekuhnen I wouldn't say that there are just two features that stand out w.r.t. NX, nor will it be correct to give that impression.
NX and Catia are two that can do extremely high end collaborative work in large team and the platforms do the entire cycle, from ideation to manufacturing. If you're a large business, and have just NX seats clubbed with SAP or some high end ERP system, you don't need anything else, provided you know how to run everything. Its like being given a bugatti veyron to go to shopping for vegetables, but if your foot lands hard on the accelerator, you'll most likely have an expensive crash.
That said, for a mid sized company that costs of going that way will be prohibitive, both in monetary and in human resources. To get productive if you were to make that choice will be excruciatingly painful. I would love to have NX in our environment, but its prohibitively expensive with all that I'd like with it, meaning, simulation tools (FEA-CFD-Motion-Experimentation-Testing), manufacturing tools etc. But how many companies will use 100% of the feature set that will come with a price tag of a few hundred thousand $$s?
I've worked with CAD systems from 1982 when there were products like Autotrol AD380 and times have moved ahead. To advice anyone to go the direction, one must first know whats their requirement (the requirements analysis), then resource capability (what they can pay for the software today, tomorrow and the day after, how much can they spend for training in time and resources, what do they already know and how would they like to fill the lacuna they have), then look at the minimum usable solution with gives them the best bang for the buck.
I would say that Fusion 360 leads the pack in the "best bang for buck" category it does 80% of what you need very well, and the remaining 19% you need you can do with a bit of effort the remaining 1% you think you need, you usually do not. That's the reason that I had chosen to demo it yesterday live in a large event organized by the municipality of the town where I live. The demo went off exceeding well. At the end I showed that a calculation done by F360 simulation gives almost the same result compare to one done by Solid Edge simulation. Although for my work, I don't use Solid Edge simulation. I use FEMAP (Siemens PLM) and NEiNASTRAN (which is now an autodesk acquisition). The impressive thing with F360 is collaboration with a team of people to enable quick development of "things".
I hope that this helps the initial inquiry and it clarifies my position.
