Duplicated NURBS Curve After Each Translation

For an Isogeometric Analysis plug-in tool we're building we'd like to be able to take an airfoil shape perform some translations then loft the curves to produce a turbine blade. An issue is that after each translation the old instance of the translated NURBS curve is left behind. For example we take the airfoil and move it 5 meters in the Z direction, there now exists a foil at (0,0,5) and one that is at (0,0,0).

How do we eliminate these redundant curves?

I've gone ahead and attached the GH file as well as some related data points. If you would like the other data for the twist and radial increase let me know and I'll include it.

Thanks in advance

Right click on the original component and de-select preview.

Also you can select multiple components and use the radial menu (Spacebar) to turn the preview off

Edit: I should elaborate Grasshopper does not manipulate actual geometry it creates a new generation. Most of the time you are only interested in the end product.

Then I suspect the issue is significantly deeper than I originally anticipated. The curve is then not lofting as it should. This does answer the original question, thanks for responding!

hey Matthew, I'm trying an isogeometric analysis with grasshoper, the thing is when I obtain the mesh (knot vectors, control points, weights, etc) and want to plot those results in Matlab, the plot is anything but the geometry I'm working on. I think when I use the SurfacePoints code, the order of the control points versus the knot vectors is not working out.. can you help me understund please?? :)
