Modeling a scene

I always wanted to do something fancy for a presentation when it came to describing how I found a scene. Sure, you can use visio, or autocad if you want to get super fancy, or even some real expensive modeling software for crime scenes. I decided to experiment with modeling a simple sample scene today in google sketchup. It took me about 20 minutes, mainly because I'm new to the program in this capacity, however I really like what this program can do. It's easy to learn, has video tutorials, and models are abundant. Anyways, I exported my model to a 2d jpg(with varying degrees of detail)because there's no way to post a 3d model that I know of. The 3d model is much much better but oh well.

What do others use for modeling a scene?
