Use the following controls in the lower horizontal bar:

- **Perspective/orthographic**

  - By default, VISOR opens models in perspective mode and hides the scale.
  - Click the camera icon to switch to orthographic mode. The view changes and the scale is displayed.
  - Click the camera icon again to return to perspective mode.

- **Cross-section**

  - Click the diamond icon to toggle the cross-section widget.
  - When enabled, the widget bounds fit the full geometry bounding box.
  - Use the 2D plane representation inside the widget bounds to change the cutting-plane location and orientation.

- **Edges/wireframe**

  - Click the grid-cube icon to toggle wireframe on or off.
  - Wireframe applies globally and does not apply per part.

- **Fullscreen**

  - Click the popout-square icon to toggle fullscreen mode.

- **Bounding box**

  - Click the bounded-cube icon to toggle the bounding-box widget.
  - When enabled, a bounding box appears around the parts in the rendering window.
  - The corners display the numeric bounds for the X, Y, and Z axes.
  - The bounding-box size does not update when you hide parts. This behavior may change in a future VISOR release.
