★★ How to customize material categories in ZW3D

Issue:

In ZW3D, material attributes are stored in the Bundles.Z3 file without categorization. 

When there are a lot of materials, it is not convenient to choose. Here is how to classify the materials.

Solution:

1. Create a new part, using the material category name as the file name, such as the Metal materials package.
   
2. Set it as the current file in Tools → Materials → File/Bundle, import a pre-defined TXT file, and click Open.
   Note: About how to define the TXT file, please refer to: ★★How to batch customize the material library in ZW3D
   
3. In a new model file, we can switch material categories from the File/Bundle.
