Export Models Up Axis

JacobAalfs — Tue, 10 Jan 2023 17:27:57 GMT

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.
