Google's SketchUp Pro version 6 includes the ability to visualise your 3D models using various 'Styles', as the guide to the new features explains -
"Styles are collections of display settings, including new options like Watermarks and Sketchy Effects, saved in the new Styles palette. You can create, save, and organize Styles as well as share Styles with others. With a single click, you can quickly apply a style to any model by selecting it from the new Styles window"
The use of Styles provides a unique way to visualise models within SketchUp, albeit with a slight performance hit. The 4 minute movie below provides a real-time flythrough of a city created by Tsa on the 3D Warehouse cycling through variety of style modes.
Note the effectiveness of the 'sketchy' feature as well as the 'blueprint' and 'tracing paper' effects:

The ability to view a city in what is almost a hand drawn mode provides a valuable way to present designs and communicate the cityscape.
Although the styles feature is only available in the 'pro' version of SketchUp you can download a fully functional version from the SketchUp site which allows a full 8 hours of use.
