Hi Salman, Note that dwg imports will always "lose" those annotation like details you add in the CAD applications. You cannot help so rather get used to it and plan your job accordingly. As for 3D entourage - now that can be the killer for SketchUp. Be very careful with it and always add these details on separate layers which you can then "turn off" and only display when you need a render (2d presentational output or export etc.)
