\*\*Hi i tried converting a gml file to 3dtiles. But i’m unable to view the tileset. I’m getting a warning \*\* **Cesium.js:472 This tileset JSON uses the “content.url” property which has been deprecated. Use “content.uri” instead.** **Cesium.js:472 Required property geometricError is undefined for this tile. Using parent’s geometric error instead.** **what could be the reason.** **I have attached the tileset.** [Building.zip](https://community.cesium.com/uploads/short-url/nLTRzjEeFYL79DNEqSpfudIrw5O.zip) (1.43 MB) ---

Do you have geometric errors defined for each tile? ---

No i don’t have any geometric errors defined.What happens if there is no geometric errors defined ? ---

Defining a geometric error is required. It’s how the client knowing when to render a particular tile or refine to its children. Without it, no tiles will be shown. Have you tried uploading your building data to Cesium ion ([https://cesium.com/ion](https://cesium.com/ion)) to get a 3D Tileset that way? ---

Thanks.I tried uploading to cesium ion.It worked. But why I’m unable to see the tileset which i have converted.This time i have defined geometric error also for the tiles.But still the same issue.Attached the tileset .

What did you use to create this 3D Tileset? There doesn’t yet exist a full 3D Tiles validator, but you can try adding the Cesium 3D Tiles inspector to your scene: viewer.extend(Cesium.viewerCesium3DTilesInspectorMixin); `` This will help show some debug properties that might make it easier to find where the issue is. Here’s a Sandcastle example showing how the inspector works: [https://sandcastle.cesium.com/index.html?src=3D%20Tiles%20Inspector.html](https://sandcastle.cesium.com/index.html?src=3D%20Tiles%20Inspector.html) I would start by visualizing the bounding boxes which you can enable under the “Display” tab. ---

Thanks for the example omar. I tried with example,I’m able to view the tileset but not able to understand why its falling in wrong place.I created the tileset using FME. **Does cesium ion uses fme for conversion?** Why the tileset is not projecting properly?I even checked the projections and transformed the projections accordingly. I’m using cesium version 1.61.Attached the source gml file. [Missouri-29029-001.zip](https://community.cesium.com/uploads/short-url/xFw4QsJ7MPIiqiaGh3KK6XmWpBN.zip) (722 KB)
