Mike and Alex from Go-2-school.com sheds some more light upon Google Sketch up in this brilliant video. The great thing about Google Sketchup, apart from the fact that its a free tool from Google, is that Google is always developing it further. As Alex mentioned in the video that Sketchup is based upon the programming language Ruby, it'll be no time before a lot of tools will be designed by programmers all over the world to enhance Google Sketchup further. This video discusses the availability of free plugins available to download from Google for free. The second part of the video will discuss those plugins further.
