@Chat Thank you for sending the asset ID. I see in the source files that the doc.kml file specifies the longitude, latitude, and altitude of the building. Is it that those values are incorrect, and you would like to input new ones? If so, you can open the doc.kml in a text editor and revise it accordingly before uploading the files to ion.
If you would like to use the Adjust Tileset Location feature to manually drag the tileset to a new location, you may upload the data without the doc.kml file and under What kind of data is this? select 3D Model (tile as 3D Tiles). This will allow you to use Adjust Tileset Location to geolocate the tileset.
Each feature needs to be a separate dae file with its own info in the kml. In that post, there’s an example excerpt of a kml file that enables per-feature selection.
You won’t be able to adjust the tileset location manually using this method, but a workaround would be to obtain the correct location through a separate step, and then put that location in the kml file. For example, you could upload the building as a non-georeferenced model, move it to the correct location using Adjust Tileset Location, and then copy the resulting lon/lat/height into your kml file.
The rvt file format is unfortunately not supported by our tilers. You will need to export your data to a supported file format before tiling. Here is some information on supported formats for your reference.
I used to export my .rvt file to supported file format such as gltf. However, it became a single file, I can’t click on the element and see its data. The element I said are door, window, floor, for example.
The point is the advantage of BIM is that it contains individual element data that is very useful. Unfortunately this advantage can’t be used in Cesium ion.
I found that the .json file contains both the model and data, but it can’t be 3D tile.
Could you please suggest how to use BIM model with individual element data in Cesium ion?
Thank you very much.

Unfortunately, we do not have a full BIM/IFC tiler that preserves metadata. The model in the BIM Sandcastle was generated separately by one of our partners.
Adding this feature is on our roadmap, but we don’t have a timeline for it yet.
The measurement and analytics widgets are not part of CesiumJS. They’re part of the commercial Analytics SDK.
You can use those widgets by getting an on-premises license for Cesium ion. Alternatively, if you just need to take measurements of your data, you can upload your data to Cesium ion and use the measuring tools in Cesium Stories. This tutorial explains how to get your data in Stories so you can make distance/area/height measurements.
