Google Sketchup is an easy-to-use 3D modelling software that enables you to create 3D models of houses, buildings and many other objects, using an array of drag and drop tools and materials in a WYSIWYG editing environment. You can design your objects with rectangles, circles, ovals, arcs, lines and freehand drawings, and use a unique push/pull tool to add dimension to 2D objects. The program offers a library of building material patterns (brick, concrete, wood, glass, carpte etc.) and colors that you can use to add a realistic look to your creation. The finished design can be exported to popular image formats, including JPG, TIF, PNG and BMP, or shared via the Google 3D warehouse. Google Sketchup does not require any 3D experience, but you should read the supplied documentation and tutorials to make full use of the software - an interactive tutorial will explain the basic functionality for each selected tool. There is also a Pro version available, that offers export to 3D and raster formats.
