Please ignore my previous question. I forgot that I was adding noise to my node values and I didn't fix the seed. Sorry for such a foolish error.

@TimStone Any chance that $ signs shifting code around in code blocks will ever be fixed? mathematica.stackexchange.com/a/219229/12
@b3m2a1 Can you let me know when the re-build was finished? Let me know if I should submit things manually.

Are there any mesh experts around?
I have a cloud of points that I'm converting into a mesh using ToElementMesh
the cloud of points is roughly convex
but I would like to introduce two slices into the mesh
this kind of geometry
into this kind of mesh
if I can just slice out a single line of triangles then that is the best

@EmilioPisanty It's a bit hard to answer without knowing how you would like to specify these lines. In any case, you can build a mesh like this: ToElementMesh["Coordinates" -> {{0.1, 0.2, 0.3}, ...}, "MeshElements" -> {TriangleElement[...], ...}] (cf. GraphicsComplex). Consequently, what you can do is look at mesh["Coordinates"] and mesh["MeshElements"] and filter out the elements that you want to keep and then reconstruct the mesh.

@C.E. thanks, that's useful!
