Layer filters are a useful tool when working with drawings with many layers. In the image below a filter has been set to show just layers that have been turned off. Unfortunately, unlike Layer states, Layer filters cannot be exported to other drawings with out of the box tools. However, with the Layer filter add-in, layer filters can be exported out to a shared location and then imported into another drawing making the process of working with many layered drawings much easier.
Fig. Layer filter tools can be located on the Add-ins tab.
Exporting a layer filter, prompts for a location with the layer filter definition saved as an IFE format file. Importing a layer filter is effectively the same process.
The layer filter add-in is free to download off the Autodesk App store and can be downloaded and installed from here:
