I think the best is to use this plugin in and "empty" file. f you make a component of what you want to bend then align the component axes according how the plugin should work then you can right click > save as... and open the new file, you can experiment without any risk then when done, in the original model, right click again and "reload".
YEP it works .... in fact , just needed an empty file ... @ Chris F. : i think the axis were changed , that was my problem !
Thanks for your help dudes!!!
