Revision colors in linked revit model

[sukhjang]

Hi,

I tried to change lineweight in linked revit model. Now, I am working with "site" file. Three building revit model are linked to that file. I just want to change the building color in site rendering and shaded view. Can I handle all lineweight and material colors in "site" file? Or, I need to change the properties in linked file.

I really need help, please..

Thanks.
