多谢高手，请继续赐教。
实现这个，我的问题就解决了。下一步把这几个数据搞到窗体中去折腾一下。
Sub bb()
   Dim p(7) As Double
   Dim lwpolyObj As AcadLWPolyline
   p(0) = 0.8: p(1) = 0
   p(2) = 1.3: p(3) = 2.1
   p(4) = 0.5:   p(5) = 2.1
   p(6) = 0#: p(7) = 0.3
   Set lwpolyObj = ThisDrawing.ModelSpace.AddLightWeightPolyline(p)
   lwpolyObj.Closed = True
    Dim curves(0) As AcadEntity
    Set curves(0) = lwpolyObj
    Dim regionObj(0) As Variant
    regionObj(0) = ThisDrawing.ModelSpace.AddRegion(curves)
    '改变其图层及颜色，并求x质心
    Dim reg As AcadRegion
    Set reg = regionObj(0)  '为何转化不成功？或者直接用
    reg.Layer = "MMM"
    reg.color = acRed
    msbox "x质心为：" & reg.Centroid(0)
  End Sub

ThisDrawing.ModelSpace.AddRegion(curves) 返回数组！
Set reg = regionObj(0)(0)'试

谢谢了。大致明白意思了。
个数组，还以为Variant是任一。
