Sounds like the file is corrupted as there is no reference to 'book' in it.
Get the file again and put the .rb file into the Plugins folder, and retry.
Don't edit it with a word-processor or similar as this might corrupt it...
The file is 'packed' and is unencrypted as it loads - I have no problems with it so you seem to have messed up something in the file's text itself ?

Have downloaded the file again and it works now!
I noticed that the file I had yesterday had a big red "Rb" on the file icon thumbnail, but it doesn't today after I redownloaded it.
I also tried other plugins yesterday and all seemed to get the same error message when loading and the big red Rb on their thumbnails, so it doesn't look like it was a single corrupted file. Weird.
But it's all sorted now. Thanks so much:p

Hi.
I've downloaded the .rb file in the plugin folder but when I restart sketchup, I keep getting a pop-up window with the following...

Error Loading File lines2tubes.rb
undefined local variable or method `book' for main:Object

This plugin would really help with my design project greatly, so I'm really hoping someone here could help me get it to work.
I'm using sketchup 8 on mac btw.
Thanks.
