How can i mirror the arrow shape not around the center axis. Not sure if I should use rotate 3d or how to define the mirror axis. I tried grabbing the edge curve of the arrow but that resulted in error. Anyways thanks in advance!
Please attach your GH file with internalized geometries, it’s pretty difficult to understand what’s going on from a screenshot with 3 components…
on a side note, I also didn’t fully understand what is your goal here 
I see the array of geometries in the shape of arrows, but I didn’t understand at all what is your final goal (even just a bad sketch of the final result would be nice!)
