Rotational Symmetry

#1

Hello, I have found a good video on using symmetry in Rhino:

However, I was wondering if there such a command as Rotational Symmetry? My building consists of two symmetrical parts, but one part is mirrored twice with regards to the other, ie it’s turned 180 degrees from the original. I need to be able to edit one surface, but see the result in both straightaway, as they depend on each other and should touch at some points.

Thank you

you can turn on history before you array it polar for example. every change will be carried to each copy made with mirror or array no symmetry needed then. history is a little limited so each new step like adding something you introduce may break it again, maybe blocks might work for this kind of matter better since they just copy whatever you have inside.

Thank you very much!
