how to use vb.net/netlink to export a dxf file

I am trying to write a vb.net program that connects to Mathematica,
performs some computation that results in a curve and exports that
curve as a dxf file. I thought the code below would work as I modified
some code I found on this site (discussion: how to save a mathematica-
made imagebox.image as jpg, gif, bmp in c#/.netlink? )

any help would be greatly appreciated. I am new to mathematica so in
case it helps to understand why I am trying to do this. I am an
architect using a 3d parametric modeling program that can execute
vb.net programs. the idea is to extend the program by using
mathematica to generate more complex curves. It could be especially
useful now that mathematica can export NURBS curves and surfaces. Very
exciting. Thanks again.

' This launches the Mathematica kernel:
    Dim ml As IKernelLink = MathLinkFactory.CreateKernelLink()

    ml.Evaluate("SetDirectory[\""C:/Documents And Settings/User/
Desktop/\""]")
    ml.WaitForAnswer()

    ml.Evaluate("gr = Plot[ Sin[x], {x, 0, 2*Pi}]")
    ml.Evaluate("Export[\""testMATH.dxf\"",gr, \""DXF\""]")
    ml.Close()
