This article explains how to use Excel VBA to control the display/hide of layers in AutoCAD.

Show/hide settings for picture layers

Basic VBA Codes

First, here is some basic VBA code to show/hide picture layers in AutoCAD.

Sub ToggleLayerVisibility（）
　　Dim acadApp As Object
　　Dim acadDoc As Object
　　Dim layer As Object
　　
　　'Get the AutoCAD application
　　Set acadApp =GetObject(,"AutoCAD.Application")
　　Set acadDoc = acadApp.ActiveDocument
　　
　　'Get the target layer
　　Set layer = acadDoc.Layers.Item("TargetLayerName")
　　
　　'Toggle layer visibility
　　If layer.LayerOn Then
　　  layer.LayerOn = False
　　Else
　　  layer.LayerOn = True
　　End If
End Sub

Detailed Description

Get the AutoCAD application using the GetObject function.
Get the current document using the ActiveDocument property.

　　'Set the layer to hidden
　  layer.LayerOn = False
End Sub
