I am an Inventor user and now our company's focus has been moved to Fusion 360. The user interface is so friendly than inventor . But what I feel is that Fusion 360 is just a modelling tool but not an engineering tool cause . Bolt designs , Chain and Belt drive generators and designs , and especially for creating configurations using iPart like in Inventor are something which should be added which is make it more of an engineering tool than just being a simple user friendly modelling tool .
This is just my opinion. I am insisting on configuration creation like iPart cause my customers have been repeatedly asking me for that
And also a concept like iLogic but should work without the dependency to know C , C++ and Java scripts like Driveworks in Solidworks should be brought atleast in Fusion 360 ultimate.
