Designing ships is a blast but I'm stuck when I want to do symmetry. There's a wing shaped like an L for the Terrans. When placed on the left of the ship it will curve down, and when placed on the right, it will curve up. I tried to rotate 90° twice but then I realized, while curving down, that it also leaned towards the front on one side and to the back on the other side.
Any way to have perfectly mirrored parts ?
