When creating a simple circuit based on a stripboard, having got it all sorted with tracks (virtually) cut and parts laid out, it's time to actually prepare the board and cut the tracks appropriately on the physical board. But you can't simply cut the tracks as shown for the part because in Fritzing the cuts appear on the top, whereas in reality they need to be cut on the underside of the board.
No problem I think. Duplicate the part and flip it so I have the mirror image and can cut the tracks according to that. But I cannot flip the stripboard as those options are greyed out. This leads to 2 questions:-
What determines whether a part can be flipped (some can) and why can I not flip the stripboard?
What would be the recommended method for cutting tracks on the underside, based on the Fritzing part that shows the cuts on the top side?
