is there a way to use a mirror modifier and make them go oposite ways like this?
what is drawn (in red & green) is not mirroring
you can do that by simply duplicating (Alt+D), translating linked duplicate (move (-X) & rotate (180° Z)) then editing the original.
PS
Now, when i think of it… would be lovely to have a macro/script.
that worked. i found another solution witch is using array and empty as object offset and rotating that. that way you get the changes in real time and not having to toggle between object and edit mode to see the changes.
