Nick,
Yes, I have seen that but I don't see a new copy of parametric.rb anywhere. The file I have and similarly on the web is from 2004. If I place it in the Plugins or Tools directories, files that need it just complain
In the error dialogue below it mentions three files, paramtric, tubealong path and weld, that it doesn't like for example
