Problem description Where do we store and find the material palette file?
Below is the workflow that needs to be followed to get the location of the material palette file.
As MS_MATERIAL is the Variable that stores the .dgnlib of the Material pallet described in the Family/Part Editor > selecting the "Parts view" Rendering properties > "Render palette".
The above image shows the list of locations where Material dgnlib is stored.
For example- Bentley_Materials.dgnlib is stored in this location (C:\ProgramData\Bentley\connectsharedcontent\materials)
