So I want to recreate Radial Mirror Addon with geometry nodes. To have this function in the modifier stack.
You can read about Addon here
Geometry node will simple modifier interface will be much easier to use.
But Blender 3.0 Geometry Nodes still missing some key features.
- Face Normal flip.
- Switcher Node to choose as many variations you like, not just True or False.
- Weld Vertex.
I found a future Blender build that has a Bisect function to slice mesh.
So if you want to try it and play with radial mirror
download the Build
and download Geo Nodes .Blend file file
