It looks like that Sunglass.io thing is possibly more about some kind of online repository for models with an integrated viewer system and an API for developers to be able to connect to it. At least that's as far as I can tell, there is not really much information about it on their site.

Some news articles are describing it as some sort of "CAD on the cloud" but it might be more like "Viewing CAD files on the cloud", and viewing files is much different than creating things. From what I can tell so far seems to be a lot of hype for something that's fundamentally a viewer system, but maybe I'm just not understanding its capabilities.

Those news articles talking about "democratizing CAD" are way over blown if it's just a viewer.
