I cannot opposite hand mirror a part which has been made with the Stock Feature
If you can please attach the part so someone can have a look at it for you.
Are you trying to mirror the part in an assembly or part file?
Unfortunately I cannot Upload the Part right Now but I am trying to mirror the part in an assembly file and it mirrors perfectly but when I change the orientation to opposite hand mirror it does not work it only mirrors the extruded parts and not the surfaces
