Autocad 3D to Revit Family

[SP-PRAJAPATI]

I made a 3d object in autocad to make a family in revit. But when I insert a autocad 3D(.dwg file) in revit family and when I explode that object, whole object select as a one object, but I want all parts as individual so that I can assign a material parameter to each parts. 

What do I have to do?

The best workflow is generally to make families from scratch in Revit, especially if you are wanting to add parameters to them.

YEah, I can make a family In revit but For a quick work and for a some smooth edge and for some complex geomatery I decided to use Autocad 3D.

Try to WBLOCK each of the objects as their separate file. Import those individual files into the Revit. When you explode, each of those objects can have independent material you can assign.

If using AutoCAD objects for your family is the correct course of action for you then take a look at your own question for the beginnings of your solution:

 Either place the individual parts on individual layers which you can assign different materials to in Object Styles, or create the different parts as separate CAD files which will give you the ability to add different materials to each CAD part (either as CAD elements or exploded to Revit elements).

Here is an example created from a vendor's CAD exports (which were then separated into multiple CAD files) and imported into a Revit family with different parts for different materials:
