My informal survey was based on anecdotal information. Since Inventor, Fusion360 and AutoCAD are all under the Autodesk umbrella it could be that many school teams/clubs lumped them all under "AutoCAD". That being said, I did hear that Fusion360 can be problematic with the cloud-based (always-on) emphasis. No mentions of Inventor, and I was also surprised that nobody mentioned Solid Edge Community Edition either.
