It's possible and very easy too, in your case just select all the edges and hit delete and the trimmed area will be deleted and revert to your original surface.
Instead of picking the edges one by one you can pick one edge and hit Ctrl-A.
Hi Danny,
woot!
Doh, now I feel very, very silly.
I had been fiddling about trying to do this for ages ( I won't say how long ;) ).
Thanks so much for all the help.
Pete
