Changing material properties of Revit Family created thru imported 3DS model

Sometimes, we may create a new family by importing 3DS Max file into Revit. But how do we change the material property of the created family?

Eventhough we cannot access the material property through the properties dialog of Revit, we can access the material setting of the imported object through Object Styles setting.

Go to "Settings", "Object Styles", then the "Imported Objects" tab. Here we will tell Revit to assign materials to those AutoCAD layers we created earlier. To do this, simply select the layer name under the "category" heading, then select the adjacent material under the "material" tab. Now you should be in the material editor and the final straight.
