How do I draw the shadow outline

Can shadows in SketchUp be captured with Ruby? And automatically outline it with a Ruby program? I hope you can provide some ideas. Thank you

If you are asking this question to get information on how to use ruby to find the edge of the shadow then you need to ask in the relevant category. At the very least in the Developers section.
You can move it there(click the pencil next to the thread title) if that is what you need.
