SketchUp bucks the trend of expensive 3D modeling software such as 3DSMax and Cinema4D and presents a free, easy-to-use alternative with which you can even post your creations onto Google Earth for the world to see. SketchUp doesn’t lack in functionality despite its ease of use, and includes all the usual collection of drawing and filling tools you’d expect, neatly accessible in the toolbar across the top of the screen. Instructor hints pop out on the right of the screen when it thinks you need them. The real fun however is when you export your sketchUp drawings into Google Earth. You can send images of your 3D designs via email or upload them for free storage at Google’s 3D Web Warehouse. Alternatively, you can geo-tag them in one-step using Google Maps, as this is integrated with Sketchup. You receive a snapshot when you add a geo-location to your model which includes 3D terrain data plus color aerial imagery.
