After stability, the biggest impediment to F360 usability is and has long been 3D navigation.
The ability to move around a design is absolutely essential to design anything, and at present it's extremely frustrating.
I suggest scrapping the current system entirely and building a new one following the following principles:
1. Panning speed should be reasonable
I'm using a MacBook Pro trackpad* and at any zoom level, it takes an absurd number of two finger swipes to move from left to right or top to bottom. Seriously look at this \/ every one of those movements is a swipe the full height of my trackpad.
It's absurd.
The pan scaling should work consistently at any level of magnification and should provide an easy way to reliably get around the scene looking at details
2. Orbiting on close inspection should behave reasonably
Once you've zoomed in to inspect a part, you should be able to easily look at different angles with minimal effort and pain. At present, the simple act of orbiting around to get a different angle can be extremely frustrating with parts flying through the view to obscure your view.
3. Overall, it should feel like picking up a part, manipulating it in your hands, moving it closer to your eyes to inspect detail or further to see the overall structure
If F360 was reliably stable and this was fixed, then almost everything else is gravy.
It's already so nearly great, it's maddening that these problems have been so persistent.
* spare me the «you should be using a mouse» and similar. There is absolutely no reason a trackpad shouldn't work reasonably. It's not only wrong, but it's insulting to criticise your users for using the software the way they want to and find most natural
