That competition was hosted by Google; you will have to ask them that question. Considering they already did campuses, I'd be surprised if they repeated it.

I don't think there are a lot of great options. Here are the one's I can think of. Create the scenes in SU, send them the file, and let them play the animation right in SU. This is probably the fastest, easiest way. Disadvantage is that depending on your model this can make for a pretty jumpy animation plus they have to have SU installed and know how to play the animation. Most user friendly would be to create scenes and do a file->export->animation and save it as an avi file or something that the other person can just click a button and play. Disadvantage is that this can take quite awhile to render the animation (turning shadows off will probably help significantly) You could basically combine those by just running through the scenes in your SU model or even just manually panning around your model while running some sort of screen capture program. This might be the best/easiest solution but the quality may suffer quite a bit so that's the compromise. I also don't know much about the screen capturing software to be able to recommend a good free one. Those are about the only options I can think of. Incidently what I do for animations is I export the animation as a series of .png files and then compile them with Adobe Premiere Elements ($99). Good quality but there's a little be of a learning curve to it if this is a one time thing. It also take a bit more time than just having SU compile everything for you and export it directly as an avi. -Brodie

If you go over to smustard, theres a ruby script called makefaces. It will fill in all the faces on the file so you can push/pull them.

@matteo said: never download the models of Max Grueter from the 3D warehouse! they kill your computer (I love the work of that guy and I'm wondering if he uses sketchup as modeller for his pieces) He uses Cinema4D for modeling his stuff. (he explained me by e-mail some time ago)

Sometimes you just simply cannot draw coplanar roof faces on certain buildings if they are not rectangular (or your roof ptch won't be at the same height). So also have a look at the plan of the building.
