Mesh: remove hard edges?

Hi @pascal,

  1. Is there a quick way to converte hard edges to soft edges in meshes? Here an example:

  1. Is there a mesh modeling (to subd) tutorial for Rhino 7?

Thanks

Hi Michael - do you mean, by ‘soft’, welded, or actually soft-shaped, like a subD? You can use RemoveCrease on a mesh or subD edge, but on the mesh here it will not change anything visually; or if you ToSubD that mesh ring, you can use Crease or RemoveCrease per edge…

But I think I am misunderstanding the question, perhaps.

Hi Pascal,

I’ve started with a quad, used _ArrayPolar, and tried to join that.

After joining the quads I still have open edges.

I am lost somehow with mesh-modeling. Hm?

How would you create this mesh ring?

Thanks

Hi Michael - the vertices are not exactly-exactly in the same locations - use AlignVertices and then Weld to get an unexplodable mesh.

Hi Pascal,

that worked, thanks.

So _Join makes me unhappy, why doesn’t it align the vertices in the modeling tolerance? Also the vertices have exact the same position, with no tolerance.

Is this a bug?

Thanks

Michael

Hi Michael - yeah, I’ll take a closer look. The vertices are not identical, microscopically, but I’d expect them to be weldable without the alignment step as well. I’ll see what I can see…

for verts that don’t quite line up, try the new stitch command… it works on meshes.
