You don't hear much about Inventor. We had it many years ago after Mechanical Desktop. But we never made much headway with it. It wasn't long after that that we went to Solidworks and Inventor fell off the radar. I wonder what kind of future Inventor has with so much development resources being dumped into Fusion?
Used Inventor/HSM since mechanical desktop. Also used Solidworks with HSMworks(before Autodesk bought it). Both very similar. Despite various bugs on both platforms, integrated CAD CAM is a huge time saver when developing/changing product design. I Have fusion, but unfortunately, fusion can't handle large assemblies, so it's out.
