Unmirror mirrored panels

[E-Key]

I created a curtain wall with aligned panels. The panels have non vertical, right aligned gap. My building is symmetrical and I'm trying to mirror these panels. But I get left aligned panel gap. Also when I create new curtain wall I get left aligned panel gap. And can't find a way to convert panels back to right aligned.
Have anybody an idea how to mirror panels?

Add a right<->left flip arrow into the family.

I'm not sure what the end design will be, but so far what you've shown would be simpler with regular walls.

Add a right<->left flip arrow into the family. Thank you for reminding me of controls. Honestly sometimes I forget to use well known features. :)
Thank you very much again!


I'm not sure what the end design will be, but so far what you've shown would be simpler with regular walls. The final task is to create a schedule of precasted panels. I think curtain wall is the best way to manage dimensions and collect information.
