In Solid Works the command is 'copy with mates'... it is a command that allows you to quickly populate multiples of the same component in an assembly. Current method is copy, past, define joint. I have 35 bolts to add to a tool design and it's taken me over an hour to get 1/2 way. VERY tedious. I am not sure how it would look / work in Fusion but a batch component copy / assemble function would be awesome.
