Smoothing a low-poly model

How do I take a low poly model and smooth it out, meaning are there commands that will aid me? When I print this, I’d rather not have a ton of post work, plus it’ll look nicer. Thank you for any help.

What kind of model is it and how was it created? Is it a mesh?

Can you upload the model? Use the vertical arrow in the toolbar above where you type your post.

How much experience do you have with Rhino?

I’m newish to Rhino. I’ve gone through most of the training vids and exercises…but I’m still learning. I believe the model was created in SketchUp.Helmet Dented.stl (781.0 KB)
I don’t believe its a mesh.

Rhino imports the contents of the .stl file as a mesh:

Valid mesh.
Closed double precision polygon mesh: 12480 vertices, 15994 polygons with normals
bounding box: (-0.399567,-0.443825,-0.563478) to (0.403649,0.398062,0.351863)

It appears that all or almost all of the facets are triangles.

I don’t know of any simple way to further “smooth” it using Rhino.

The shape could be recreated with a much smaller number of NURBS surfaces in Rhino.

Thank you for your help, I appreciate it.

maybe try the ReduceMesh command, you can nicely play with the amount of reducing, to the level of detail you need, after that you get a better chance to rework it maybe.

Thank you, I’ll try that
