the most powerful and imaginative I work with is FormZ

a lot of incredible tools !!

Inventor is a excellent CAD but the subdiv Tspline tools ( idem in Rhino 5 ) are binding ( contraignants in french )

and the assembly mode is a pity

FormZ contains the major part of the wishlist here in Moi forum ;)

( perfect communication with Moi ) transferts of complex stuff in seconds through Step format

just my opinion ;)
