Google Sketchup
May 16th, 2006Google purchased @Last Software and has released a free version of their SketchUp 3D modelling software. Google SketchUp main page.
A Pro version is available for $495 and supports additional file formats, high resolution rendering, and other features.
This is intuitive and extremely easy-to-use software.
In the screenshot of the free version SketchUp, below, I’ve been piling on and extruding through a box with random shapes. With the paint bucket tool selected, animated context-sensitive help appears.

For free models, visit the Google 3D Warehouse.
