Developing a light, but powerful module for 360 that enables full offline use, without forcing too much load on the GPU, should be essential. The development of a design suite that uses offline toolboxes, and saves models offline, would open a whole new world of possibilities for Fusion 360. By creating a light-weight module that could be used on any CPU and GPU combination could open the market towards adapting the module to iOS. By implementing Apple's recently launched METAL API, the application would be powerful, but lightweight, and could enable a true Hand-Off experience. Being able to translatate the lightweight API from the iOS F360 App to OS X's Full F360 graphics engine is definitely a must for Autodesk.
The iOS app could be a completely independent F360 Engine (name that could be used for the mobile engine: "FusionMetal"), and could employ iCloud as syncing mechanism for models designed on OS X and models designed on iOS. Being able to bring a model truely to life on my iPhone is something I look forward, and I know that Autodesk is capable of unleashing a Fusion Revolution.
This simple approach towards capturing an idea on-the-go, and being able to use the power of an iPAD or iPhone 6 Plus, will revolutionize the current envisionment of the iOS devices in the engineering, architecture, and design business.
