vba旋转生成实体

求VBA旋转生成实体语句，如一个平面的圆绕一个轴旋转后生成圆环


，就是这个图标的语句。谢了！

谢了，就是这个东西，我的开发要完成了

Sub Example_AddRevolvedSolid()
      Dim cc As AcadCircle
      Dim ptc(0 To 2) As Double
      Dim rc As Double
      ptc(0) = 0: ptc(1) = 0: ptc(2) = 0
      re = 5
         Set cc = ThisDrawing.ModelSpace.AddCircle(ptc, re)
    ' 创建面域
    Dim regionObj As Variant
    regionObj = ThisDrawing.ModelSpace.AddRegion(cc)
   
   
    ' 定义旋转轴
    Dim axisPt(0 To 2) As Double
    Dim axisDir(0 To 2) As Double
    Dim angle As Double
    axisPt(0) = 10: axisPt(1) = -5: axisPt(2) = 0
    axisDir(0) = 10: axisDir(1) = 5: axisDir(2) = 0
    angle = 6.28
      
    ' 创建实体
    Dim solidObj As Acad3DSolid
    Set solidObj = ThisDrawing.ModelSpace.AddRevolvedSolid(regionObj(0), axisPt, axisDir, angle)
    ZoomAll
End Sub
这又是这么回事？
按照你给的代码修改的
