Hi Michael,
When I renewed my license for V4.0 (just at the time of its release), the French aid was still that of 2010. I understand very well that it certainly takes time and work for the translators so that all help in all languages is up to date with help in English. I have now done what is necessary to update the latest French documents available in the "Docs" folder.

Regarding the "Cut" function: using a line or a curve, it is possible to cut on a solid or a surface from any view. But to cut a curve or line from another line or curve, I noticed that it doesn't work in 3D view, and only works in other views if those are the one behind the other. This is not documented it seems to me.
(I don't know what the GG translation gives ??!)
