Automating DWG to Models

We are an autocad shop. Our designers like using sketchup to make custom room layouts for our customers. I was wondering if anyone knows a way that I could automate creating sketchup models or items from DWG’s? In an ideal world our designers would have all of our “standard” parts as items that they could add to a drawing as well as create custom stuff. I would also love to be able to know when a drawing contains a standard part.

Any help would be great!
