指定视口的扭转角度。

支持的平台：仅限 Windows

签名

VBA：

object.TwistAngle

对象

类型： PViewport

此属性应用于的对象。

属性值

只读：不

类型：双

以弧度为单位的扭转角。

言论

此方法会扭曲或倾斜视线周围的视图。AutoCAD 逆时针测量扭转角度，向右 0 度。

例子

VBA：

Sub Example_TwistAngle()
    ' This example creates a new paper space viewport.
    ' It then displays the twist angle of the viewport.
    
    Dim pviewportObj As AcadPViewport
    Dim center(0 To 2) As Double
    Dim width As Double
    Dim height As Double
    
    ' Define the pviewport
    center(0) = 3: center(1) = 3: center(2) = 0
    width = 40
    height = 40
    
    ' Change from model space to paper space
    ThisDrawing.ActiveSpace = acPaperSpace

    ' Create the pviewport
    Set pviewportObj = ThisDrawing.PaperSpace.AddPViewport(center, width, height)
    pviewportObj.Display True
    ThisDrawing.MSpace = True
    ThisDrawing.ActivePViewport = pviewportObj
    ThisDrawing.Regen acAllViewports
    
    ' Find the twist angle for the viewport
    Dim twistAngle As Double
    twistAngle = pviewportObj.TwistAngle
    MsgBox "The twist angle of the paper space viewport is " & pviewportObj.twistAngle, , "TwistAngle Example"

End Sub
