Oh right. I did that but for some reasons I though it was uneditable... I think I'm a bit slow..!
Thank you very much for your response and advices

Hi to all,
First of all, thanks to everyone in the Sketchup community, I'm new to it and I discover really fair people. Now to TIG, thank you for this great plugin, really powerful, a masterpiece ! A free masterpiece !
Unfortunately I'm too young here to send MPs so my request will be public.
Actually I have to teach Sketchup and I would like to put the "roof" plugin into the process. Issue : I'm french and not everyone understand english (especially technical terms), is it possible to get the "unscrambled" version so I can traduce it in french ? If it's possible I would be pleased to upload it here with your agreement.
Thank you in advance.
Larry
