I've seen some other suggestions related to features that would make this software more intuitive for people who are not machinists. I had a suggestion.
Apple used to do something very neat when evaulating how intuitive or easy to understand their products were. When they introduced an interface change, they had a room where they would take users, give them a list of tasks to complete, and then film them (or watch through the 2 way mirror). They had a lot of really amazing revelations with this approach (it's actually why the Apple symbol was upside down on laptops for so many years - when put in the room, customers would always turn the apple towards them and try to open it the wrong way. Ultimately the fact that it looked stupid on TV trumped that, but there you go.)
What I'm seeing with F360 is that you have a community of engineers and machinists who are already using similar tools in similar ways and are pretty much looking for specific refinements to the product, they already know what they are doing and what they want. And then there are the other groups like me, coming from sectors like desktop publishing and are really having a hard time understanding how to do the simplest things (today I'm trying to bang out 16 different name plates for Christmas, something that would take me 20 minutes in photoshop, and I haven't finished on yet because I can't figure out how to select the top of my recessed text to make a chamfer on those edges...well, a way that doesn't involve me command clicking 20 times for each S in a name.)
I think it would be amazing if you brought in new users from different industry sectors and watched them, see what are the particular points and concepts that are causing roadblocks. There's a whole world of people eyeing those 3D printers and CNC routers, with a whole universe worth of ideas. Anything you can do to make the tool more accessible to us would be amazing.
