You can share custom materials with other users by making them available in a material library that is shared.
You can share material libraries with other Revit users on your project team or other project teams. Material libraries can also be shared with other Autodesk products, such as Autodesk Inventor and Civil 3D. If you want to access a material from another user-created library, first load the library in Revit, and then add the desired materials to your project.
If the desired material library does not display in the Material Browser library list, you need to load that library. To load a material library, your computer must be able to locate and access the ADSKLIB file that defines the library.
The selected material library displays in the library list. Now you can copy materials from that library into your projects or into other user libraries.
To share a material library that you created with other users, make the ADSKLIB file available to those users by sending it to them. The ADSKLIB library file for Revit 2024 is typically located here by default:
Users who want to use this material library can place this file anywhere on their system; however, it is best to place it in this location for consistency.
