Copy Objects to Layer

Demonstrates how to copy objects to layer based on Python.

Python

import rhinoscriptsyntax as rs

def CopyObjectsToLayer():
    "Copy selected objects to a different layer"
    # Get the objects to copy
    objectIds = rs.GetObjects("Select objects")
    # Get all layer names
    layerNames = rs.LayerNames()
    if (objectIds==None or layerNames==None): return

    # Make sure select objects are unselected
    rs.UnselectObjects( objectIds )
    
    layerNames.sort()
    # Get the destination layer
    layer = rs.ComboListBox(layerNames, "Destination Layer <" + rs.CurrentLayer() + ">")
    if layer:
        # Add the new layer if necessary
        if( not rs.IsLayer(layer) ): rs.AddLayer(layer)
        # Copy the objects
        newObjectIds = rs.CopyObjects(objectIds)

        # Set the layer of the copied objects
        [rs.ObjectLayer(id, layer) for id in newObjectIds]
        # Select the newly copied objects
        rs.SelectObjects( newObjectIds )
