After calling
> /project/api/v3/projects/{id}/
, there is one column name “offset\_3d\_xyz” with the value of [440000, 3970000 ,0]
I can guess that it’s a coordinate of 3dModels but where exactly? the center of the model? the base?
I can’t find any document on this too, so, please tell me if you know where should I be looking at.

Hi @moonblood.game.1,
They offset.xyz refers to _the offset between the centered points and the output coordinate system. It can be used for the textured mesh (.obj file) and densified points cloud (.ply and .xyz file). This is the difference between the local coordinate system in which some of the outputs are created and the output coordinate system._
