3Dconnexion Navigation Library Server is a background component installed with 3Dconnexion’s 3DxWare drivers. It acts as a bridge between 3Dconnexion input devices (such as SpaceMouse models) and supported 3D/CAD applications, exposing the Navigation Library interface so software can receive six-degrees-of-freedom (6DoF) motion data and button events. The service typically starts with the operating system, runs quietly with low resource usage, and handles device connections, per-application profiles, and input routing to plug-ins and clients. You may see it listed as 3DxNLServer.exe in system processes.
For most users with a 3Dconnexion device, this service is required for full navigation functionality in compatible applications; stopping or removing it can disable those features. If you don’t use a 3Dconnexion device, it can be disabled or uninstalled along with the 3DxWare package without affecting other software.
3Dconnexion Navigation Library Server is developed by 3Dconnexion. The most popular versions of this product among our users are: 1.0, 1.1, 1.2 and 1.4. The names of program executable files are 3DxHome.exe, 3DxPair.exe and 3DxSmartUi.exe.
