Google SketchUp 6.0.277 for MAC

This program moves beyond napkin sketching to communicating ideas in 3D. SketchUp takes what may traditionally be seen as a complicated task and adds an intuitiveness many design programs fail to achieve. On first impression, this sketch-based 3D-modeling program may look as if it has sacrificed function for simplicity, but that's not the case. Despite the extremely user-friendly interface, SketchUp offers a suite of powerful 3D drawing tools that lets you experiment and play with new designs. All actions are carried out using two button bars, one that runs down the left side and another that sits along the top of the work space. After you simply sketch and draw edges, the application fills in the objects to create 3D geometry. SketchUp handles perspective and alignment calculations automatically. You can then export these objects into CAD, 3D-modeling, image-editing, illustration, or animation programs for further manipulation and editing. Functionality and price mark this for professional use, but curious amateurs may enjoy exploring the demo.
