When you have all those trailing zeros, it's a sign that it is computer 
generated.
My guess is that the scene dimentions is in the milimeter scale, with 
base unit defined as meter.
Using a base unit of 1 cm would be beter,  and 1 mm would probably be 
optimal. Also, there is nothing to prevent you from using 0.01 mm as a 
base unit. That way, all values, but one, becomes integers.
