Hello, I have two files in cesium ion, one is a kml file and another is a 3d tile file, what I want is to put them together, but the next thing you see in the image happens, I would like to know how to clamptoGround the KML file on the 3d model, does anyone know how to achieve that or have an idea?

Clamping your entities to ground should be sufficient, here’s an example where a line from a CZML is clamped to 3D Tiles:

The only additional thing for KML is that, in addition to the entities in the KML file itself having clampToGround, you must set clampToGround: true when loading it in CesiumJS:

Let me know if this works.

It didn’t work, it still looks the same, and I’ve already added the clampToGround: True

Can you share a Sandcastle example I can run showing the issue?


As far as I can tell, the lines in the original KML need to have the right altitude mode set (to clamp to ground). Here’s a Sandcastle that will override this setting to always clamp all the lines.

This dataset looks very cool! What kind of project are you working on with Cesium?

**Hello, a while ago you helped me as some 3D tiles, do you think that now this 3D  ****Cesium.IonResource.fromAssetId(8403)** **tile can still be pasted to the floor and put this id clamp to grouound on the 3d model**

Can you share a Sandcaslte of your asset here?

Yes, this is the Cesium Sandcastle

Hello, sorry for the inconvenience, I have already put my cesium sandcastle where I put my 3d model to clamp to ground to the ground, but it seems that the Z coordinate does not work

Hello @Erubey_Martinez,
I saw your 3D tiles model in the sandcastle and it looks pretty cool ! I was wondering how you generated the 3D Tiles files (as there seem to be very few tools to generate them properly)?
