If you are doing 3+2 programming, you aren't missing much with NX. It has some great tricks up it's sleeve for very specific situations, but honestly? Fusion is way faster to learn, easier to templitize for your environment, and you can go buy a nice car with the price difference between it and NX. I think we're getting to the point of maturity in the industry where 3+2 programming and turning tools are basically all interchangeable; the real competition is in 5 axis, mill/turn, additive, machine simulation, robotic machining... all areas where NX is either the leader of the class or sitting in the front row area. But if 3+2 milling is your end goal, save your money.
NX CAD is a different story. I think it is objectively the best CAD system in existence and even the base Mach 1 seat that comes with the 3 Axis milling package is a beast that makes Fusion or SolidWorks look and feel like toys.
OK, so this is the point where the conversation became interesting...,
Just like the OP, I am/was a longtime FeatureCAM user with perpetual license on maintenance.
In addition, I am/was also an Autodesk Inventor PDSU user with a perpetual license on maintenance.
Even though ADSK stopped selling perpetual licenses back 2015, they have grandfathered in the existing Perpetual licenses and allowed us to remain
updated as long as we've not let our maintenance elapse.
Well, as of May 7, 2021, ADSK has switched to the Named User license scheme, and as a result we were/are no longer able to pay for our perpetual license to remain up-to-date.
So, I am ( and likely a few others as well ) now looking for which direction to go with when the time comes....
While the OP is looking to add something to help with immediate needs, I am guessing he is also looking to make that to be something "perpetual"
He does have an active FeatureCAM-Ultimate subscription, which means he has full access to everything Fusion has to offer. By everything Fusion, I mean EVERYTHING FUSION!!!
And yet, he is asking for something not ADSK, and quite possibly not rent-A-software ( SAAS if you will )
Well, so am I!
Since allowing both of my ( Inventor PDSU and FeatureCAM Premium ) licenses expire, I have saved over $8K, only to be put towards to whatever comes next.
My needs are 95% 3+1 milling and 5% full 3D. No 5 axis, no additive, not even 3+2 or mill/turn, even though I have that with my FC-Premium package...
At the same time, I also will need a new CAD platform as well.....
So, in that realm, what - if anything - does NX has to offer?
( Gregor: Sorry to somewhat sidetrack your thread, but we are somewhat in the similar boat !!! )
