任意两条多义线,如何得到他们的交点.
或直接求两条多义线的面积(主要用于公路中填挖面积的计算)

Dim intPoints As Variant
intPoints = lineobj.IntersectWith(circleobj, acExtendNone)

' Print all the intersection points
Dim I As Integer, j As Integer, k As Integer
Dim str As String
If VarType(intPoints)  vbEmpty Then
      For I = LBound(intPoints) To UBound(intPoints)
         str = "Intersection Point[" & k & "] is: " & intPoints(j) & "," & intPoints(j + 1) & "," & intPoints(j + 2)
         MsgBox str, , "IntersectWith Example"
         str = ""
         I = I + 2
         j = j + 3
         k = k + 1
      Next
End If
