Hi,

I am trying to upload an tiled model from Agisoft Metashape to Cesium ION. The error is “Unsupported datum transformation.” The project is in local coordinates coresponding to Czech national systems - but in Metashape it is just an ordinary cartesian system, nothing special except negative values for both X and Y coordinates. This is needed for the proper orientation of the model.

When I try to upload the tiled model in WGS-84, there is another error:  
Response code: 404  
Response data: {“code”:“ResourceNotFound”,“message”:"/v1/assets"}

Any idea if the error is related more to Cesium or Metashape and how to solve it? Thanks.

Filip

854975

But this is already newly calculated in wgs-84 system.

Hi @flogs,

Thank you for sharing your asset ID number. To the best of my knowledge, we do not currently support that type of transformation. I recommend checking out the following guide for our supported 3D Tiling formats.

> **[3D Tiling](https://cesium.com/learn/3d-tiling/)**
