Thank you very much! You provided just enough for me create my first Ruby SketchUp script (it makes cylinders) and I figured out how to integrate it with SketchUp..all in just a few hours..lol! It was an ideal challenge--I feel like I'm off and running! I should mention, for the sake of anyone reading this, that some background I had in O-O programming and some reading I did about Ruby, were invaluable too. I just registered at this site and I am looking forward to learning more about programming for SketchUp here.
