Thanks Dawn, glad you found it useful. When I saw everyone else chipping in with edge loops and Lightwave stuff, my efforts looked a bit feeble; but it seems I hit the right level, so thanks for replying. This was all fresh in my mind, since I'd recently done exactly the same procedure to cut the front of an open shirt out of a continuous mesh. Anim8or is mentioned in my existing tutorials when a modeller is required, but I deliberately haven't gone into it very deeply, since they weren't meant to be Anim8or specific. I've meant to do one for some time, which probably means I'll never get around to it. :)
