Mesh split Bad R7

Hi, there is a problem When using mesh split . Not working well

@piac Hello, please :rose:

Hi @PowerShape

the mesh has a lot of t-joints, and as such these edges are naked in Rhino. How did you construct it?

Thanks for the quick answer.
Is there a quick way to fix this.
I tried to fix this, but it didn’t work .
I used another program . Stitch mesh | PowerShape 2020 | Autodesk Knowledge Network

That mesh can easily be drawn by constructing a unit (using _3dFace) and repeating that minimal unit enough times.

Later, it must be joined (_Join) and even later welded (_Weld) properly, and that can be more tricky. I used an upcoming feature of V8 for fixing the joining of edges because _AlignVertices in V7 seems to have some problems with so many faces.

EDIT: @PowerShape, here is the improved mesh, also split.

The Rhino command for this is called MatchMeshEdge. It can work, currently only on smaller meshes.

My colleague @BrianJ brightly mentioned that also ReduceMesh → “Planar Only” will work in this case to fix the mesh. That’s a possible solution for this mesh in Rhino 7. It’s coincidental that the problem happens in a planar face, and is thus fixed tangentially by this command, but it’s still better than nothing.
