[求助]如何得到两条多义线的交点

fjfhgdwfn

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)

fjfhgdwfn

 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

 2桉的方法好象不行，能否再更新一下，运行时会提示每二行的问题“此处需要物体”

本人也在找一个求多边形各顶点的方法，不知道可否赐教，多谢
