I know that by using CTRL + M it’s possible to flip an object.
But I now need to flip several objects, each with its own angle.
Here’s a mockup of the scenario
Each object has its own center properly setup.
What I tried is, select all of them, enter edit mode, and then the usual flip with CTRL + M followed by Y.
That didn’t work:
Maybe I should use the 3D cursor, but I cannot figure out how to do it.
Basically, I’m trying to get something like this:
Any idea?
Maybe just use one of this and use and empty to array rotate and then flip just one… ??
Well, the actual model I’m dealing with has different shapes/sizes for each element.
I simplified it only for the mockup.
There are also several rows of these elements, and their position offset per each row.
Not sure it’s actually possible…
Okay… then of course… (i read mockup but thought… just as a replacement for one repeated object)… you are out of luck 
… and “just” have to do it… for every single object…
Probably a way to do this with geometry nodes but I’m not sure
If i get you correctly: setting transform orientation to local, and transform pivot point to individual origins will give you ability to frip all objects by rotating to 180deg.
Yes of course… 
sometimes someone doesn’t think of the simplest things… actually the first image shows that the pivot point is not in the center of the objects but in the object… so now local… and
