object.ElevationModelSpace

对象

类型：数据库、文档

此属性应用于的对象。

属性值

只读：不

类型：双

模型空间的高程设置。

言论

当前高程是每当需要 3D 点但仅提供 X 和 Y 值时使用的 Z 值。当前高程分别在模型空间和图纸空间中维护。

例子

VBA：

Sub Example_ElevationModelSpace()
    ' This example changes the model space elevation of the current drawing
    ' and then resets it to the original value again.
    
    Dim currElevation As Double
    
    currElevation = ThisDrawing.ElevationModelSpace
    MsgBox "The current model space elevation is " & ThisDrawing.ElevationModelSpace, vbInformation, "ElevationModelSpace Example"
    
    ' Change the elevation
    ThisDrawing.ElevationModelSpace = currElevation + 2
    MsgBox "The new model space elevation is " & ThisDrawing.ElevationModelSpace, vbInformation, "ElevationModelSpace Example"
    
    ' Reset the elevation to its original value
    ThisDrawing.ElevationModelSpace = currElevation
    MsgBox "The model space elevation is reset to " & ThisDrawing.ElevationModelSpace, vbInformation, "ElevationModelSpace Example"

End Sub
