CAD on the Cloud – available anytime, anywhere except when it isn’t

One of the multiple reasons Autodesk has failed to win over the masses to its Cloudy CAD vision is fear of unreliability. Anything that relies on using somebody else’s computer over the Internet adds potential points of failure to those already there on a standalone desktop system.
