Not sure if anyone has seen this so I thought I would pass this on, Google has a free easy to use 3 Dimensional Rendering program called SketchUp 7. I have started to use it to design wrought iron railings and other furnishings for clients to see exactly what they will get. It is easy to use and Google has lot's of tutorials. You can find it and download it for Windows & Mac at http://sketchup.google.com/ and the startup tutorials are there as well.
