Need help flipping multiple objects in a collection as a whole Hi guys, i'm still new in blender and i'm currently trying Hard-Ops non destructive modeling, i have an issue on mirroring a collection as a whole, if i try "right click -> mirror" it will mirror based on each of the objects individual origins (which is a mess). 



I also tried putting the origins to the head and ctrl+m to mirror it but it still ends up super messy

Below is an attempt to mirror the objects by 3D cursor as a pivot point



How do i mirror them as a one whole object? i've been scratching my head this whole day haha, any insight will be much appreciated :)
I might be missing something but the problem seems simple to me.

With your first described attempt you were using Individual Origins.



But I think you want to use Median Point while mirroring, and you'll get the desired result.
