Google SketchUp is a tool used by everyone from the new mom figuring out a layout for the baby room to professional movie preproduction teams on films like Inception, 300, The Social Network, and Tron: Legacy. There is the free version that gives you a great variety of tools and the Pro version which has even more advanced features. Filmmakers have been using SketchUp but were limited by many things including camera options. Now Google has updated their popular modeler to be helpful for filmmakers.
