SketchUp is popular 3D modeling software by Google. It’s easy to use and powerful too (well don’t expect some breathtaking results from it as you could with 3D Max, for example).
Google SketchUp Pro 6 is software that you can use to create, share and present 3D models. The Pro version of SketchUp provides extra functionality for people who need to export their work into CAD, rendering and other professional software applications. SketchUp Pro 6 also includes LayOut, a completely new program that lets you create complete presentations—paper and digital—from your SketchUp models.
Google SketchUp Pro 6 now lets you create 3D models from photographs, match existing models to background photos, render sketchy effects and fog and mark your models with 3D text, logos and watermarks. With the new Styles palette, you have easy access to a collection of display settings, which you can save and share. You also have greater control, with new features like enhanced modifier keys that let you perform operations like “copy” while you move, rotate or push/pull.
