Rotate 方法（ActiveX）

围绕基点旋转对象。

支持的平台：仅限 Windows

签名

VBA：

object.Rotate BasePoint, RotationAngle

对象

类型：所有绘图对象、AttributeReference、尺寸

此方法应用到的对象。

基点

访问：仅输入

类型：变体（双打的三元素阵列）

3D WCS 坐标指定旋转轴定义为平行于 UCS 的 Z 轴的点。

旋转角度

访问：仅输入

类型：双

旋转物体的角度（以弧度为单位）。此角度决定了对象相对于其当前位置围绕基点旋转的距离。

返回值（RetVal）

无返回值。

例子

VBA：

Sub Example_Rotate()
    ' This example creates a lightweight polyline
    ' and then rotates that polyline.
    
    ' Create the polyline
    Dim plineObj As AcadLWPolyline
    Dim points(0 To 11) As Double
    points(0) = 1: points(1) = 2
    points(2) = 1: points(3) = 3
    points(4) = 2: points(5) = 3
    points(6) = 3: points(7) = 3
    points(8) = 4: points(9) = 4
    points(10) = 4: points(11) = 2
    Set plineObj = ThisDrawing.ModelSpace.AddLightWeightPolyline(points)
    plineObj.Closed = True
    ZoomAll
            
    MsgBox "Rotate the polyline by 45 degrees.", , "Rotate Example"
    
    ' Define the rotation
    Dim basePoint(0 To 2) As Double
    Dim rotationAngle As Double
    basePoint(0) = 4: basePoint(1) = 4.25: basePoint(2) = 0
    rotationAngle = 0.7853981   ' 45 degrees
    
    ' Rotate the polyline
    plineObj.Rotate basePoint, rotationAngle
    
    ZoomAll
    MsgBox "Rotation completed.", , "Rotate Example"
    
End Sub
