I'm beginner in allegro and I'm having trouble with placing components. I want to move some components from top side to bottom side of board, but I don't know how to do this in allegro.
open allegro pcb editor
do the following
edit -> mirror
and click on the component to mirror.
eg: if u want to place lot of by-pass capacitors on
bottom layer do the following
place -> manually -> Components refdes ->
select the refdes and click mirror in the (control panel Options)
