TIG is right of course but With Dynamic Components you can do almost everything you want to do.
Try opening the Dynamic Components toolbar, (view > toolbars > dynamic components) select the hand (interact tool) and click on the guy that shows up when you open Sketchup 2013 (Derrick).
Then go activate view > hidden geometry and click with the interact tool again and see what happens.
Insert some more Dynamic Components from the component browser. Insert some more DC's from the Google Warehouse. Search about DC's here or at Sketchup website.
Try a lot, fail a lot and you'll succeed!
Best regards,
