The materials library contains a vast array of materials that you can apply to elements. Even so, you may find that you want to customize it at some point in time.
In the materials library, materials are listed in groups (Concrete, Brick, Wood, etc.) so you can organize and find them easily. You can add, rename and delete groups as needed. You can add new materials to the library, as well as edit and delete existing materials.
If you customize the catalog materials library (through the Catalog Manager), your change is saved with the catalog. If you customize the project-specific materials library (by editing an inserted element), your change is saved in the current project only.
To access the catalog materials library:
Select File > Catalogs > Catalog Manager, or right-click an element in the catalog panel and select Catalog Manager.
In the Catalog Manager, select Libraries > Materials. The Materials dialog appears.
To access the project-specific materials library:
Select an element in your drawing.
Right-click and select Properties.
In the properties dialog, select the Appearance tab.
Click the Select button. The Materials dialog appears.
