Ok folks, so I just downloaded and installed Google Sketch Up 8 and played around with it for a few minutes. It's pretty cool but it leads me to yet another question and that is how do I save something so it can show up in RW?

First you must export it to a main modeling program such as Blender to 3D Crafter Pro, or Blender all together, then you complete it there. Sketchup unfortunately can only do the beginning, it is unable to do everything.
