Exploding RhinoCommon HiddenLineDrawing segments

So once I have computed my HiddenLineDrawing, I have a collection of segments which are stored in .Segments…

    hdp=Rhino.Geometry.HiddenLineDrawingParameters()
    hdp.AbsoluteTolerance=sc.doc.ModelAbsoluteTolerance
    [hdp.AddGeometry(sc.doc.Objects.Find(objID).Geometry,"") for objID in objIDs]
    hdp.SetViewport(vp)
    hdp.Flatten=True
    hld=Rhino.Geometry.HiddenLineDrawing.Compute(hdp,True)

    #enumerate the collection of segments
    for i,seg in enumerate(hld.Segments):
        #this works
        crvID=sc.doc.Objects.AddCurve(seg.CurveGeometry)

However, some segments are polycurves I would like to explode… And I haven’t figured out how to turn the “HiddenLineDrawingSegment+HldCurveProxy” into RhinoCommon curve geometry so that I can explode it…

All I have been able to do so far is add the unexploded curve to the document as my scriptlet example above, and then explode it with rhinoscriptsyntax methods… which I would like to avoid if possible. I assume there has to be something simple I missed for doing this?

Edit: BTW, after compute, I can get hld.Segments - that is the only thing that seems to work though - I cannot seem to access hld.Objects or hld.FullCurves as it seems I should…

Thanks,
