I would like to point you to two more videos that have been posted on youtube. The first shows how various UI elements can be dropped onto simple SketchUp models, in this case a chair, to turn it into a professional looking product sales tool.
This can be found by following http://www.youtube.com/watch?v=QASQulLZJq8
The second shows how the further use of drag & drop Smart Objects can add real time post-processing effects - pen & ink, slate & chalk, water color etc - to models in just a few seconds. This one uses an architectural street scene and can be found at
I do hope that these are of interest.
