A Navigation Mesh (or shorter: nav mesh) is a data structure that stores data used for path finding, which is typically used by bots. In 
Source, navigation meshes are used by the following entities:
…to realize what's navigable in their environment, and path to their desired destination.
NAV files
Main article: NAV
Navigation Mesh data is stored in a NAV file corresponding to the map file (.bsp) for which it is used. For example, the nav mesh for cstrike\maps\de_dust.bsp is stored in cstrike\maps\de_dust.nav.
Main article: Nav Mesh Editing
Main article: Nav Mesh Commands
The Navigation Mesh Editing is done in-game. A (new) .nav file can be generated with nav_generate (which requires sv_cheats 1 and nav_edit 1).
