Viewport label menus are located at the top-left corner of each viewport, and provide a convenient way of changing views and visual styles.

By default, text is displayed that shows the current viewport settings. For example, the text might be
[+][Top][2D Wireframe]
You can click within each of the three bracketed areas.
- Click + to display more options
- Click Top to choose between several standard and custom views
- Click 2D Wireframe to choose one of several visual styles. Most of the other visual styles are used for 3D visualization
