Is there a way to modify which axis is up when a model is exported?

I understand in the cityengine model up is the y-axis (even thought it is displayed as the z-axis). Further, when the model is exported up is in y coordinates.

So when I modify the Geometry Settings of my export as shown below, does modification effect the real coordinate or the ESRI psuedo-coordinate? When I set the Z-Offset to be -100, am I really changing the exported y-coordinate?

Hello @JacobAalfs 

Thank you for your questions. 

  • The models are always exported as y-up. 
    Some formats (like FBX) have an attribute field to store the up-axis. For OBJ the convention is y-up.
  • On Export the Global Offset gets applied to the Global (Scene) Coordinates.
