Maybe you can try the OBJ format if your object is a pure quadrangles subdivision !
Maybe also decimate...before!

Direct conversion by the native SubD / Creat from File don't work for this case!
or by Import OBJ (by max Smirnov)
and you will have exact quadrangles to nurbs conversion following a %

With the original i am affraid that you can't make something with a such file! :)
here the importOBJ

Thanks a lot FP,
a first step. I try to moi-model a horn.

---

It's a start.
I think I should create the sweep using multiple profiles, not just one. What do you think?

You could use this process :

Extract profiles selecting each segment of each profile.
Those profiles will be closed curves and polylines
apply A rebuild or reconstructcurve to have closed curves with only 1 segment. (A smooth version of your profiles)
Use a point for the last segment to have a pointed surface

Use all profiles and the last point to loft a clean surface.

Hey, the model is triangulated because the STL format is for 3D printing, I think.
So I imported the model into Blender, went into edit mode, selected all the vertices, and used the Alt+J shortcut to turn the triangles into quads.
Now you can import the model using the SubD command in Moi3D and recreate the horns more easily. I’m attaching the obj model.

There are still some triangulated small zones, but is almost quad now

Hello Phiro,
Thanks!
“A rebuild” or “reconstructcurve” don't seem to do anything for me. But maybe I'm not selecting the right lines. Or do I need to install a script first? Because otherwise, I'd have to click on every single line segment one by one.

Hi Paf,
Thank you so much for your great dedication and for helping me with this. I'll try Phiro's approach first, and if I get stuck, I'll try yours.

---

ok - ready. Thank you very much!
