Hello TIG
I installed from your link and it works fine...
Thank you

In fact on the current version there is the regex pattern and the =~ operator on the same line, that's why I separated it, so to find which part the error comes from...
At this time I could not use this extension because of this error.

Hello
I wanted to use 2D Tools extension
I got the error :

Error; #<ArgumentError; invalid byte sequence in UTF-8>
C;/Users/LRT/AppData/Roaming/SketchUp/SketchUp 2017/SketchUp/Plugins/deBabelizer.rb;134;in `=~'

That comes for the second line :

s=/<==>/
if txt=~s
   set=txt.split("<==>")
   sets<<set
end#if

It seems that sketchup doesn't recognize the tilde when reading this file.
When I write the tilde into the Ruby console it works.(with the same test)

As my file is UTF-8 encoded, why is there that error ?

Hello
Is it possible to name a shape or a dimension into a component?
Let suppose I have a rectangle with many round holes.
Is it possible to name some of the hole's diameters, so I can change them, and only the ones with that name, with a script ?

Thank for help.
