As someone who uses Inventor, do you think it would be worth it to transition to Fusion?
For me, who uses Inventor once or maybe twice a year for maybe 3-4 weeks at a time and who uses $15 of Inventor, I would say yes. Every time I load it up I spend a day re-familiarizing myself with it, and I know that many of my habits are not best practices. Inventor is a DEEP ocean.
For someone like you, who is MUCH more familiar and CAD-oriented, maybe not. But even still you would need to learn alot of powerful complimentary tools to have the same "basic" functionality as Fusion. For example, Inventor HSM and TruNest.
For creators who want to figure out the basics on how their model goes together and want to easily prototype it themselves then Fusion is the tool I would probably start with. For people like me who just want to hand over the concept to experienced engineers who know what tool to use and the difference in cost between 32 degrees and 31 degrees, then Fusion is great. If you are that experienced engineer, then you probably don't want to invest your learning time into Fusion, but then again, you wouldn't be reading this either.
