I have made a two layer pcb, imported all my components from schematic but cannot seem to be able to place components on either side of the board. For example all are positioned on top side, I need to more some to the bottom side. There doesn't seem to be a way to do this, if I use Q, it changes the symbol but not the component, if I select the component, right click on it, there is no option to swap it to the other layer. Any ideas / suggestions please
