I am trying to cut a sheet metal part so that it matches up to a bent tube for welding (see attached screenshot).

I have tried both a Swept cut and a surface cut, which both cut the part how I want but neither have a "normal" option for the cut thereby making the sheet metal part unfoldable.

I could make normal cuts using the surface cut edges for reference, but thats kind of a long way to do it, is there no way to normal cut like this?
