Hi I have a finished pcb but I have one problem with it. It only has two layers (top & bottom) but they are round the wrong way i.e. top layer should be bottom layer and vice versa. Is there an easy way to change this? It is because there is surface mount pads on the top when they should be on the bottom. Im a newbie so please have patience with me. Thanks...

The hard way ;-)

all commands typed in the command line, except #4 ... 6:
1) set used_layers all, enter
2) group all, enter
3) mirror, enter
4) Ctrl + RMB (does the mirroring)
5) F7 (move)
6) Ctrl + RMB to move the origin of the group back to coordinate x=0, y=0

Hint: maybe problems arise if you are using the freeware version. The
allowed area for placing & moving components is restricted to 1/2 Eurocard
(80x100mm). Choose an appropriate starting point for moving.

or try: mirror-board.ulp (ulp-folder)
