The software certainly spits out a SA number, buts its not the same number that you will arrive at measuring by hand as shown above. They can be different for a number of reasons, some of which I do not fully understand yet myself. If they gave you a number from their computer, its not a number likely to be recreated when someone attempts to measure that sail by hand.
When my in laws redid their kitchen, the counter guys did the measurements by laser.. I wasn't there, but my FIL (who was an Apollo project rocket surgeon for both Rockwell and Grumman) told me it was pretty slick... they had some pretty odd angles along with an island that had an arched side (leech) and the finished product fit like a glove right down to the mm when they installed it...
I am wondering if this technology could work for us?
