# Transform Gizmo
The Transform Gizmo lets you move, rotate, and scale a loaded asset directly
inside the 3D viewer. It opens as part of the Transform subsection inside the
Scene Layers panel whenever you expand a layer that supports transforms, such as a
3D Tileset or a Model.
### Features
* Three editing modes: Move, Rotate, and Scale, that you can switch between at any time.
* Color-coded axis handles in the viewer so you always know which direction you are editing along.
* Click and drag editing in the 3D scene, with the active axis highlighting in yellow as you drag.
* Numeric Offset, Rotation, and Scale inputs in the side panel for typing in precise values.
* A live coordinate readout showing the asset's longitude, latitude, and height above terrain.
### How to Use
1. Click the "Layers" button in the Top Toolbar to open the Scene Layers panel on the right side of the viewer.
2. Expand the group that contains your asset, such as 3D Tilesets or Models, then click the chevron next to the asset name to open its inline detail panel.
### Choosing a Mode
At the top of the Transform Properties sub-panel you will see three buttons.
Click "Move" to switch the gizmo to translate mode so you can drag the asset along an axis.
Click "Rotate" to switch to rotate mode so you can spin the asset around an axis.
Click "Scale" to switch to scale mode so you can resize the asset.
The active mode highlights in blue so you can tell at a glance which mode you are in.
### Dragging in the Viewer
The gizmo shows three colored axis handles. Red is X / East, green is Y / North, and blue is Z / Up.
Click and drag a handle to apply the active mode along that axis, and the selected axis will highlight in yellow while
you drag.
Release the mouse button to commit the change and the asset will keep its new transform.
### Using the Numeric Inputs
Below the mode buttons you will see fields for Offset, Rotation, and Scale.
Type a value into an Offset field in meters to nudge the asset along X, Y, or Z.
Type a value into a Rotation field in degrees to rotate the asset around X, Y, or Z.
Type a value into the Scale field to resize the asset.
Click "Apply" to push the typed values to the asset in the viewer.
### When the Gizmo Is Not Available
The Transform Gizmo only appears for asset types that support 3D transforms — 3D Tilesets and Models. If you expand a
layer such as an Imagery Layer, Terrain, or a Data Source, the Transform subsection still shows but its inputs are
greyed out and the "Apply" button is hidden, since there is nothing to move in 3D space.

## 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/transform-gizmo.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.
