Being free, it also obviously lacks some of the advanced features of many of its heavyweight rivals. Most annoying is when trying to create domed surfaces because of the cumbersome nature of the Extrude tool, although pushing and pulling straight lines is considerably easier. There are some problems with SketchUp however.

The Shadow Settings palette is also worth keeping to hand, as it allows you to apply realistic shadows via simple sliders. Of particular note is the 'Materials' palette, which contains over 100 different preset swatches, such as vegetation, metal and glass. Other options can be accessed via the menu system, or you can choose to place extra palettes on the workspace to save wading through menus. Instructor hints pop out on the right of the screen when it thinks you need them. SketchUp doesn't lack in functionality though 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. You receive a snapshot when you add a geo-location to your model which now includes 3D terrain data plus color aerial imagery.

Alternatively, you can geo-tag them in one-step using Google Maps which has now been integrated into Sketchup. You can send images of your 3D designs via email or upload them for free storage at Google's 3D Web Warehouse. The real fun however is when you export your SketchUp drawings into Google Earth.
