Does IntersectWith work with 2011?  If not what is the fix?  Apparently I cannot find the apparent intersection point of two lines.


If I try to use IntersectWith, I get an error that it is obsolete.

it's not an error, it's just a warning, as far as i know


Public Sub IntersectWith(ByVal entityPointer As Autodesk.AutoCAD.DatabaseServices.Entity, ByVal intersectType As Autodesk.AutoCAD.DatabaseServices.Intersect, ByVal points As Autodesk.AutoCAD.Geometry.Point3dCollection, ByVal thisGraphicSystemMarker As System.IntPtr, ByVal otherGraphicSystemMarker As System.IntPtr)


if you use integers as the last 2 parameters, you get the obsolete warning, use System.IntPtr instead

Thanks this worked for me.


        'Setup 3d plane and point collection
        Dim myPlaneWCS As Plane = New Plane(New Point3d(0, 0, 0), New Vector3d(0, 0, 1))
        Dim myIntPntCol As Point3dCollection = New Point3dCollection()
        Dim myintptr01 As IntPtr = New IntPtr()
        Dim myintptr02 As IntPtr = New IntPtr()


        'Get intersecting point collection
        objFirstLine.IntersectWith(objSecondLine, Intersect.ExtendBoth, myPlaneWCS, myIntPntCol, myintptr01, myintptr02)


        Dim pntIntPnt As Point3d
        'Check if number of intersecting points is one
        If myIntPntCol.Count = 1 Then
            'Create a new point from intersecting point
            pntIntPnt = New Point3d(myIntPntCol(0).X, myIntPntCol(0).Y, 0)
            MsgBox("Intersecting error.", MsgBoxStyle.Critical, "")
            Exit Sub
        End If
