propably more complicated response
But the question go to this, if set all reference point - can orient and use in proces, then when exporting, could i get detailed info about ratio between pixels/cm ? that mean if need to use it for detailed plans of some buildings - ruins, i can just calculate pixels and then i get the right size - lenght, diameter in real size.....
we test it for use in old ruined castle and making from it construction plans - will upload later this week some examples.......
