That is glacier Bay in Alaska, we did the Alaska/inner passage tour/cruise in 2008 great trip, by theway. Everybody needs to add that to their bucket list. It is STUNNING to say the least. Just do it from North /South so it is land first and glaciers/whales/seals second, a rising crescendo!!!!!! As to the autocad I will try and help much as I can.
