求助 面域布尔运算 赋值时报错 ——类型不匹配

将47，50 ，51 加引号注释就运行很好 ，求高手帮忙看看 这个却运行的很好，不知道上面那个程序是哪里错了Sub Ch4_CreateCompositeRegions()

' 从地板空间中减去柱子的空间
' 以得到代表总的地毯面积的面域。

' 使用Area属性以确定总的地毯面积
MsgBox "地毯面积为: " & RoundRoomObj.Area
End Sub D:\Capture.JPG 程序运行附图 AddRegion返回的是数组/variant
不是数组的成员！！！！
regions(0) = .AddRegion(outcircle) 这当然不对了！
还有Dim A, B, C, D As AcadRegion，把ABC也定义成AcadRegion,而不应该是variant
