You are welcome.
I was confused too at the beginning, but after examined tons of codes from others and bunch of trial and fails, read the forum… started to make sense, and the picture is starting to come together (sort of). I’m still not a programmer, but I feel more comfortable to understand the docs and codes.
I find now the doc is more or less okay.
(BTW if you didn’t know there is a link in doc to “official” GitHub sketchup-ruby-api-tutorials, with commented examples:
File: SketchUp Ruby API — SketchUp Ruby API Documentation )
Your examples are “oversimplified” 
, so I’m not sure what you really want to achieve, or just showing?
It is not “drawing things” just print outs to Console…
You may take a look on my old “thinking out loud” topic…
Never mind, you are more than welcome to create a topic in Developers - Ruby API category and ask specific questions. (This category is monitored by me more than other categories - I guess by Dan and Thom too.)
