Why can't it rotate according to my idea?

[y_yyy]

Good afternoon!

I would really appreciate for some idea.I’m a student of architecture and also a beginner in Rhino.I’m trying to create an exterior facade like this picture,but I’m having a problems during the rotation process . What should I do to achieve the correct rotation?

For better help, share the definition with internalized geometry.

When you rotate the objects, you need to specify the plane/center of rotation. Currently they all rotate around the same point.

Thanks for your reply.

I tried to separate each edge using listltem ,but why does it still rotate around one side of my large plane?

It’s hard to guess whether your intention is to rotate the geometry around the edge (the script) or around the center point (Leopold’s idea).

If you want rotate the geometry around one of it’s edges - here is the cleaned up tree structure

you can rotate it in four planes
