Underground Navigation
The underground navigation mode allows you to explore the subsurface of the terrain. You can navigate under the terrain’s surface and through buildings. A subsurface grid navigation aid appears when you navigate below the terrain, allowing you to navigate the same way as above ground.

To fly in underground mode:
1. On the Home tab, in the Navigation group, click Underground Mode.
2. Use any of the techniques mentioned above to navigate in the 3D environment. You can freely go through the terrain surface in any direction.
