Is their a "How to Guide" or a Manual on how to add tunnels in surveyor I have 2010EE and haven`t got a clue , when i try to lay a tunnel and then lift the surrounding grassed area to cover it ,it blocks the track inside with grass in the tunnel as well , Basically I just dont know what i`m doing when it comes to adding tunnels and could do with an online guide .
