Unlike object references in JavaScript or VBScript, AppleScript object reference names do not 
remain constant. Refer to an AppleScript language guide or text book for information on 
referencing a file using either as alias or to a reference to file. 

Layers("Layer 3").Select

layers["Layer 3"].select() //using the collection name and square brackets for the 
collection

Existing layers can be moved into layer sets. The following examples show how to create a 

Layer Set

 

object, duplicate an existing 

ArtLayer

 object, and move the duplicate object into the layer set.

set current document to document "My Document"
set layerSetRef to make new layer set at end of current document
set newLayer to duplicate layer "Layer 1" of current document¬

to end of current document

move newLayer to end of layerSetRef

In AppleScript, you can also duplicate a layer directly into the destination layer set.

set current document to document "My Document"
set layerSetRef to make new layer set at end of current document
duplicate layer "Layer 1" of current document to end of layerSetRef

In VBScript you must duplicate and place the layer. 

Set layerSetRef = docRef.LayerSets.Add
Set layerRef = docRef.ArtLayers(1).Duplicate

layerSetRef.Move appRef, 0 'for psElementPlacement --> 0 psPlaceAtEnd

layerRef.MoveToEnd layerSetRef

In JavaScript you must duplicate and place the layer. 

var layerSetRef = docRef.layerSets.add()
var layerRef = docRef.artLayers[0].duplicate(layerSetRef,

ElementPlacement.PLACEATEND) 

layerRef.moveToEnd (layerSetRef)

Scripting also supports linking and unlinking layers. You link layers together so that you can move or 
transform the layers in a single statement. 

make new art layer in current document with properties {name:"L1"}
make new art layer in current document with properties {name:"L2"}
link art layer "L1" of current document with art layer "L2" of ¬
