    Default INTERSECTING POINT

    I am trying to find the intersecting point between two lines that cross over each other, like a cross. I have tried the .intersectswith method but it seems to only find a point where one line begins or ends on the other line. Below is the code I am using.
    Code:
    Private Function LinesIntersect(line1 As Line, line2 As Line) As Nullable(Of Point3d) 'As Tuple(Of Point3d, String) 'Nullable(Of Point3d)
            'Try
            Dim ls1 As New LineSegment3d(line1.StartPoint, line1.EndPoint)
            Dim ls2 As New LineSegment3d(line2.StartPoint, line2.EndPoint)
            Dim inters As Point3d()
            Dim colI As New Point3dCollection
            Dim x As Boolean = False
    
            inters = ls1.IntersectWith(ls2)
            If IsNothing(inters) = True Then
                MsgBox("****")
    
                inters = ls2.IntersectWith(ls1)
                If IsNothing(inters) = True Then
                    MsgBox("**** 2")
                    Exit Function
                End If
            End If
    end function
