About 3D Tiles conversion and guide

I have a question about 3D Tiles conversion and guide.

We would like to inform you that an error occurred when converting to 3D Tiles and that there is a place to organize (reference) the guide.

[example]
3DS → 3DT tile
CITYGML → 3DTILES
IFC → 3DTILES
OBJ → 3DTILES
Point Cloud → 3DTILES

thank you

I’m not entirely sure what the question is.

an error occurred when converting to 3D Tiles

Does this refer to data that you uploaded to Cesium ion, and that could not be converted into 3D Tiles?
