Hi Didier!
I can't make your new commands work.
Some quotations from console:
Error: #<NameError: uninitialized constant ProjectCpointTool>
C:/Program Files/Google/Google SketchUp 7/Plugins/projection_extension.rb:47
C:/Program Files/Google/Google SketchUp 7/Plugins/projection_extension.rb:47:in call' Error: #<NameError: uninitialized constant XLinesThrougLinesTool> C:/Program Files/Google/Google SketchUp 7/Plugins/projection_extension.rb:23 C:/Program Files/Google/Google SketchUp 7/Plugins/projection_extension.rb:23:in
call'
Any ideas what's wrong in my case?
And thank you again and again for your contributions.
