Batch Rename Layers in Rhino Using Python Script

Problem

When working with multiple layers in Rhino, we often need to batch rename layer names. Especially when layers have parent-child hierarchy structures, we might only want to modify the endpoint layer names rather than the complete hierarchy path.

Solution

Implement layer name batch replacement using Python script. Key points include:

1. Use rs.LayerNames() to get all layers
2. Extract endpoint layer name via split("::")
3. Perform text replacement using replace()
4. Rename layers with rs.RenameLayer()

Core Code

import rhinoscriptsyntax as rs

def replace_layer_names(old_text, new_text):
    layers = rs
