This is the set of instructions I have been trying to use.

The Ruby scripts are in the plug in folders.....named correctly , show different sizes.... some come zipped , some not...
but in looking at my buttons ... I can not find any that indicate my Ruby downloads have reached Sketchup...
and they do not show in the Ruby console... in Sketchup 8
Thanks,Greg
