Naked Edges and non manifold edges when using flow along surface

Rhino
1

Hi! I am making a cylinder with a pattern by using the flow along surface command, a lot of issues are created where the two outer edges roll up and meet to create the cylinder.

Is there any command to identify non-manifold edges or anything I can do to boolean the overlapping inaccurate edges?

Thanks

show edges set to nonmanifold will highlight them for you.

as for fixing them, I’d have to see the file to give you any useful advice.

Hey, thanks for the info… maybe I’m asking the wrong question.

My final object I’m working on is a closed polysurface (there are no non-manifold edges when I checked). when I export it as a 3mf to print in my Bambu 3d printer it says the plugin has failed and it won’t export. I then exploded the object and then joined everything back together and then it exported fine (it still says its a closed polysurface). then when I open the 3mf in Bambu it says there are non manifold edges that need to be fixed.

I think it will still print, and maybe it’s nothing to worry about, but it’s just annoying when I put a bunch of work into trying to make the object correctly!

This object is part of a set of four pieces and every other piece exported fine with no error messages or non-manifold edge error stuff. It’s just this one piece that has an issue

any advice you have would be awesome, thanks

I use step files in my bambu…

but… the best way to export meshes to a printer are to mesh them specifically using the mesh command. That way you can examine the mesh and make sure that everything looks good.

here’s a video breaking down all the settings-

and this one as well-

or the nuclear option, shrinkwrap-

Wow! Thanks so much, this is super helpful. I will give it a go.

Really appreciate it
