Freeze 属性（ActiveX）

指定图层的冻结状态。

支持的平台：仅限 Windows

签名

VBA：

object.Freeze

对象

类型：图层

此属性应用于的对象。

属性值

只读：不

类型：布尔

True：冻结图层。
False：解冻图层。

言论

冻结层使它们不可见，并将它们排除在再生和绘图之外。解冻图层可实现这些功能。关闭或冻结图层上的 AutoCAD 曲面和圆是不可见的，但在使用 HIDE、SHADEMODE 或 RENDER 命令时，它们仍会隐藏对象。

不能冻结活动图层，也不能使冻结图层处于活动状态。

此属性与属性不同，因为在再生期间不会生成冻结图层。LayerOn

例子

VBA：

Sub Example_Freeze()
    ' This example creates a new layer called "Freeze".
    ' It then displays the status of the Freeze property
    ' for the new layer, toggles the status of the
    ' Freeze property, and again displays its status.
    ' After running this example, you can check the layer
    ' control on the Object Properties tool bar. It will
    ' show the new layer and the latest Freeze status.
    
    Dim layerObj As AcadLayer
    
    ' Create the new layer
    Set layerObj = ThisDrawing.Layers.Add("Freeze")
    
    ' Display the Freeze status of the new layer
    GoSub DISPLAYSTATUS
    
    ' Toggle the status of the Freeze property for the layer
    layerObj.Freeze = Not (layerObj.Freeze)
    
    ' Display the Freeze status of the new layer
    GoSub DISPLAYSTATUS
    Exit Sub
    
DISPLAYSTATUS:
    If layerObj.Freeze Then
        MsgBox "Layer " & layerObj.name & " is frozen.", , "Freeze Example"
    Else
        MsgBox "Layer " & layerObj.name & " is thawed.", , "Freeze Example"
    End If
    Return
        
End Sub
