Hi Pilou,

> For have the original I must cut incline ;)

So yes, go ahead and cut it then! :)

There is no rule that you must only accept the result of an extrude and cannot modify it by cutting.

It cutting is necessary, then draw a line and cut it...


> But you agree all that don't arrive if original generator were keept!

Yes, not without an additional cut - that means to draw a line in and do a boolean difference to slice it at the angle you want.

I'm not entirely sure if the actual desired shape is an extrusion with a cut end though, or a shell with a cut end.

Normally to get constant thickness you use shell, but since this is not heavily curved the difference is pretty small for this case.
