Whether you need an exterior wall built, an interior wall, or are having trouble with an oddly-shaped wall, this tutorial will clear everything right up. Not only does it show you handy tricks, such as using the rectangle tool to draw walls instead of the line tool to ensure accuracy and efficiency, but it also walks you through step-by-step on how to build walls in Google SketchUp. And for added reinforcement, everything the narrator demonstrates is also shown along the bottom of the screen in written text. So after a little more than six minutes, you'll be having all kinds of fun with walls in SketchUp and learning how to draw them, delete them, change them, and well, just make them better!
