2024-5-18 18:45| 发布者: admin| 查看: 373| 评论: 0|原作者: admin|来自: AutoCAD

在 WCS 坐标中指定布局或打印配置的原点。

支持的平台：仅限 Windows

签名

VBA：

object.PlotOrigin

对象

类型：布局、PlotConfiguration

此属性应用于的对象。

属性值

只读：不

类型：变体（双精度的双元素数组）

X 和 Y 值表示相对于媒体左下角的原点。

言论

原点与介质边缘的偏移量为纸张边距。使用该方法查询边距。原点以毫米为单位。GetPaperMargins

在重新生成图形之前，对此属性的更改将不可见。使用该方法重新生成图形。Regen

例子

VBA：

Sub Example_PlotOrigin()
    ' This example reads and modifies the PlotOrigin
    ' Layout value.
    ' When finished, this example resets the  value back to
    ' its original value.
    
    Dim ACADLayout As ACADLayout
    Dim originalValue As Variant
    Dim newValue(0 To 1) As Double
    
    ' Get the layout object
    Set ACADLayout = ThisDrawing.ActiveLayout
    
    ' Read and display the original value
    originalValue = ACADLayout.PlotOrigin
    MsgBox "The PlotOrigin value is set to: " & originalValue(0) & " ," & originalValue(1)

    ' Modify the PlotOrigin preference by toggling the value
    newValue(0) = originalValue(0) + 20
    newValue(1) = originalValue(1) - 20
    ACADLayout.PlotOrigin = newValue
    MsgBox "The PlotOrigin value is set to: " & newValue(0) & " ," & newValue(1)

    ' Reset the preference back to its original value
    ACADLayout.PlotOrigin = originalValue
    MsgBox "The PlotOrigin value is set to: " & originalValue(0) & " ," & originalValue(1)
End Sub
