I found this great plug-in on the vectordepot web site, called the Frangisole (sunshade). This tool is designed to create simple sunshades.
The interface is really easy to use. You draw a line to define the length of the sunshade, and use the Object Info Palette to change the number of horizontal parts, the height, angle and width of the boards.
If you tilt the boards to the correct angle, you can make siding (weatherbords). If you use some simple solid modeling, you can cut out the frangisole for doors and windows.
To see it in action, have a look at this short youtube vid.
Subscribers to Vector-workout Subscription will find a detailed movie for this plug-in in the July manual.
