Asset Transformer Studio **Viewer** panel is where geometries are displayed and can be manipulated (selection, transformation, visibility…):

* **Scene axis**: Gives information about the scene orientation. Asset Transformer Studio viewer is Y-up oriented, and right-handed. Red is the X-axis, Green is the Y-axis, Blue is the Z-axis (\[X,Y,Z] > \[R,G,B]).
* **Part occurrences** (3D objects): are displayed accordingly to the viewer settings defined in the Studio Toolbar, **Edit** menu and the Preferences (F9)
* **Scene grid**: brings a visual help to evaluate objects orientation and objects scale. By default, the grid size is 2 meters large.
* **Viewer Information Board**: displays information regarding the loaded model: occurrences (parts) and triangles (polygons) count. Use the shortcut F3 to quickly show/hide this board.

> **Note:**
>
> Asset Transformer Studio provides a robust & powerful viewer, necessary to display and manipulate numerous complex 3D data, as industrial CAD models are.
