# 3D Tiles
3D Tiles are the streaming format the viewer uses for large meshes, photogrammetry models, and lidar derived datasets. Once a tileset is in your library you can load it into the scene, fly the camera to it, then transform and style it from the Scene Layers panel
### Where they live
Open the asset library from the side panel and find your tileset in the list. Each asset card shows the file name on the left and a small source tag
underneath telling you whether the data is from your AeroAI library, your Cesium Ion library, or a local entry.
#### Load the tileset
Click the cloud download icon on the left side of the asset card to bring the tileset into the scene. The icon turns into a blue check once the data has
finished streaming in, and the card highlights to show the asset is active.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.aeroai.io/siega-web-features/asset-library/data-layers/3d-tiles.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
