good evening,
is it possible that there is an issue with welding ngons with 4 sided mesh faces or is it my fault?
thx

hey,
obviously i am not able to weld these 4 mesh faces too. usually adapting the angle tolerance works like a charme.
what I am doing wrong?
cheers,

Hi Benjamin.
Your mesh has tow pairs of coincident vertices which can be stitched using _Stitch
Is this what you expect to see or did I miss something?

hey Martin,
thanks for your fast reply! the result of the naked edge analysis is as expected. there where 4 faces and two of them welded.
uh, i didnt know the stitch command, just tried “weld mesh” and “weld mesh vertices”, shouldnt they work in this case?
stitchmesh does not work either, or I am just to tired today?
nice climbing walls btw! 
cheers,
Benjamin
Thanks!
A Stitchmesh command does not exist in Rhino as far as I can see.
Your mesh does not contain any unwelded edges.
Weld | Rhino 3-D modeling (mcneel.com)
According to the help file, _WeldVertices should weld the vertices and I don’t know why that’s not the case on your mesh.
hey Martin,
there is a stitch command for meshes in rhino, but i cant select two edges for the stitch, because they are too close together.
somehow the standard commands dont work either, i have no clue, propably it has to do with tolerances, whatever.
this is just a small example out of a larger mesh and I dont want to remodel it. WIP 8 is not welding the vertices either.
thank you,
Benjamin
If you’re referring to the command in the Mesh tab, then that is the same stitch command I was using.
I just tried again.
I ran _MeshRepair first and then _WeldVertices and that seemed to work.
The mesh now has 10 vertices.
You get this info with the _What command
good morning Martin,
thank you for your effords, i tried to check the mesh like you and had interesting results:
after repairing it:
nakes edge analysis:
welding vertices:
mesh normals:
i somehow dont get it.
this is the combination with a ngon after unifying mesh normals (a good mesh btw):
have a nice day,
Benjamin

Not sure where things go wrong on your side. I think Rhino 8 has a lot of improvements when it comes to meshes. But I see the normals are bad on this latest file too.
Try _RebuildMeshNormals

ok, that looks much better. propably the mcneel guys know whtas happening here.
thanks you for your support!
