Thank you :slight_smile:

I have some experience in making a similar graph. I would suggest:

  1. fit the point cloud to surf.
    – You can first convert the point cloud to mesh by ShrinkWrap, then MeshToNURB if using Rhino8.
    – Also, you can use patch to fit a surface through point cloud, but you should expect some loss in the point cloud’s information. (set a higher U and V, 10 by default is usually not enough)
  2. Contour the surface you got in X and Y (not like usual in Z), and save the lines to a picture
    – Using ScreenCaptureToFile under Arctic (_-SetDisplayMode, M, A) display mode is the easier way.
    – if you are using software like Adobe Illustrator to post process it, use Make2D will give you well defined 2D NURB curves ready for a copy.
  3. without rotating the object, render your surface under a well defined lighting environment, to get a nice grayscale image of the same viewpoint.
  4. In photoshop, use the saved contours as mask on a colored image to create the grid, or just use your Adobe Illustrator output. Overlay it onto the rendered grayscale. Add the tags and highlight points accordingly.
