先忙代码是图片1的,图片2的代码改怎么写
Public Sub Sub3DObjWithUCS()
    Documents.Add

    '创建一个正方体实体
    Dim objBox As Acad3DSolid
    Dim lenOfBox As Double, widthOfBox As Double, heightOfBox As Double
    Dim cenPntOfBox(0 To 2) As Double
    cenPntOfBox(0) = 100: cenPntOfBox(1) = 100: cenPntOfBox(2) = 50
    lenOfBox = 100: widthOfBox = 100: heightOfBox = 100
    Set objBox = ThisDrawing.ModelSpace.AddBox(cenPntOfBox, lenOfBox, widthOfBox, heightOfBox)

    '以该正方体顶面中心为原点,建立一个用户坐标系
    Dim ucs As AcadUCS
    Dim origin(0 To 2) As Double
    Dim xA(0 To 2) As Double
    Dim yA(0 To 2) As Double
    origin(0) = cenPntOfBox(0): origin(1) = cenPntOfBox(1): origin(2) = cenPntOfBox(2) + heightOfBox / 2
    xA(0) = origin(0) + 1: xA(1) = origin(1): xA(2) = origin(2)
    yA(0) = origin(0): yA(1) = origin(1) + 1: yA(2) = origin(2)
    Set ucs = ThisDrawing.UserCoordinateSystems.Add(origin, xA, yA, "MYUCS")
    ThisDrawing.ActiveUCS = ucs
    Dim ucsMat As Variant
    ucsMat = ucs.GetUCSMatrix

    '在该用户坐标系中创建一个球体
    Dim objSphere As Acad3DSolid
    Dim sphCenPnt(0 To 2) As Double
    Dim sphRadius As Double
    sphCenPnt(0) = 0: sphCenPnt(1) = 0: sphCenPnt(2) = 0
    sphRadius = 45
    Set objSphere = ThisDrawing.ModelSpace.AddSphere(sphCenPnt, sphRadius)
    objSphere.TransformBy ucsMat

    '改变视口的观测方向
    Dim newDir(0 To 2) As Double
    newDir(0) = 1: newDir(1) = -1: newDir(2) = 1
    ThisDrawing.ActiveViewport.Direction = newDir
    ThisDrawing.ActiveViewport = ThisDrawing.ActiveViewport
    ZoomExtents
    ThisDrawing.Regen acActiveViewport
    ThisDrawing.SendCommand "shademode G "

    MsgBox "将进行差集操作..."

    '进行差集运算
    objBox.Boolean acSubtraction, objSphere
    objBox.Color = acCyan
End Sub
