How can I connect the top loop to the down loop with faces Hey I want to connect the bottom loop with the top loop so that it forms a solid.

I have tried selecting multiple vertices and pressing F but that just creates a large face which I do not want.
I have tried using grid fill bu that doesn't work either.
The solution that seems to work is by selecting four vertices and pressing F and then selecting the next 4 and pressing F and on and on. That just takes too long.
You should use Bridge edge loops command:


Select both loops:



2.Then click space and type bridge edge loops:
