Oh, rest assured that FC is dead, just not buried yet.
And the only reason it isn't buried yet is they (ADSK) is trying to milk whatever is left in the userbase, as that is in fact one of the primary
income to finance the Fusion development.
FC, Powermill, Partmaker and a host of other packages serve the very same purpose actually.
The funny thing is, they try to peddle Fusion on their very own forums, attempting to lure over existing users of FC, Powermill etc.
Well, the resident Fusion Idiot tried to pull the same stunt on the Inventor forum, only to be handed his hat in very short order from a bunch of long time
and serious Inventor users.
He got the beatdown so bad that not only did he take his toys and go back to the Fusion forum, but all traces of the few threads have been completely removed from the Inventor board.
