how to get a downloaded dwg model to render in my dwg file?

after i download dwg models they show up the wrong size and a solid green colour when I insert them to my drawing. I think I may work out how to get the scale right but how do I make it so I can attach a material and render it within my scene?

it might be a xref or is might be a block reference then just explode it and then try to render the objects
