Hi. I am new on this forum and hope to learn a lot and collaborate on Rhino with everyone.

I have a pretty cool mesh object of an IL-86 (Russian airliner from the 1980s). I want to convert the mesh to a smooth surface so that I can refine it and create a mesh with smaller size panels suitable for 3D-printng.

I tried tracing curves from each point, which is manageable process. However, I began to wonder how I was going to use these curves to form surfaces? If I trace horizontal curves down the length of the fuselage, then trace vertical curves for cross sections, I wind up with a very good curved outline of the fuselage. The problem with this technique is that the vertical curves and the horizontal curves do not necessarily intersect with each other. Therefore, its not really conducive to creating surfaces. Maybe this is the proper technique, but I am doing something wrong?

Next, I downloaded T-Splines, and ran the command: “Convert Nurbs or Mesh to T-splines”. It did transform the topology to T-splines, but I am not sure what to do next. After running the command, it seemed to result in a mesh that looked exactly the same as what I started with – except now it was composed of T-Splines.

I was hoping that this command would take all points and generate a smooth curve that represented a best fit for a particular row or column of points --> then join them to result in a smooth surface.

I have heard that creating converting a mesh to a surface can never be fully automated. Which is OK with me. I was just thinking that it would give me starting point, that I could use as my base; then refine it manually.

I don’t see how I can post a picture, otherwise I would post a screenshot.

Thank you in advance for any help or insight that anyone can offer.
