Here is the txt file I'm loading. (It's a json file from the beginning.)

test1.txt

Are you running this in the Ruby Console, or in some other console extension ?
Try this without the ' def'


filepath = UI.openpanel("Open File", "C;/", "TXT|*.txt||")
if filepath ### allows user to Cancel
  settings = File.readlines(filepath)
  puts settings[2].split(' ')[1].to_f
else
  puts "Canceled!"
end

Our posts crossed.
Both my versions of the code work fine with your TXT file, with no error [in Ruby Console].
So do you use a console-app ?

Pixero

Interesting.
Running your latest code in the console works but running it in SketchUp Ruby Code Editor by Alexander Schreyer gives the Nil result also.

I also tried your first version in the console and it worked without errors.
So is it safe to continue if it's just something in his Code editor app that causes the Nil result?

Most of these console-apps are not perfect...
I only ever use the Ruby Console.

Thanks for all the help so far. I'm sure there will be more later on...
If only the Ruby console was multi lines. It's hard to edit in the small window.

TIG

I always edit my code in a Notepad++/TextWrangler window [with Ruby text-highlighting], then I copy/paste it into the Ruby Console's bottom bar + enter, to run it.
The Ruby Console accepts multi-line code if pasted, but you can only manually type in one line at a time!

I use Notepad++ as well but use the ruby code editor when testing out snippets without having to restart SketchUp.
Now I’ll continue with the main work.
