I know Alexey, and I do...it's just when I know my photos have GPS data AND a compass heading...it's not like Agisoft seems to ignore that data - if that was the case then I would expect some models on their side, some the right way up etc...but they are ALWAYS upside down.
It's as if Agisoft says..."Yeah, I know which way is "up"...but because you didn't pay for Pro, I'm not going to randomly orientate your object. I'm just going to put it on it's head. Because you're poor."
