Sketch Up - Gaudi's Swimming Pool

Here's a theater space I've been noodling with in Sketch Up; I want the surfaces to be a bit more flowy and droopy and "organic" but I like the idea of the whole shebang being covered with ceramic tile stuck in the side of a hill somewhere. I also envision it being covered by triangular tarps for inclement weather, but have yet to add those elements. After I started playing with this idea it began to remind me of a swimming pool ala Gaudi.
I was having a devlish time trying to get one of the raised sections to raise up in the audience area. I stillcan't figure out why it won't raise up like I got the other sections to. Whatevs.
