I was wondering if there was a free program I could use to help with designing, in a 3d environment.
Google offers a free 3D program called Google SketchUp. This free program download gives you the ability to create, modify and share 3D models. Depending on the type of application, you may need to invest in a rendering program. Google SketchUp offers a variety of rendering options. Google also offers a paid program called Google SketchUp Pro that provides a suite of powerful features for design and engineering professionals. At Fire Mountain Gems and Beads, our 3D department uses a paid for program called Autodesk® 3ds Max® Design 2012. To view some of our 3D examples, see the link below.
