hi,
I am an architecture student and for a course of mine i need to 3D print an object. To be able to do that I need to split a mesh in half. I tried every command I know but non of them worked. Even returning the mesh into a polysurface and wire cutting it afterwards did not work.
Thank you in advance!

do you have a version of this object before you tried to split it? it seems you have saved the partially failed attempt here which does not make it easier but probably even more difficult. also you have overlapping meshes, maybe thats also from the failed attempt.
Hi Emma - the mesh is 'valid; but messy - if you look at the base, closely, you’ll see there are a lot of overlapping faces:
If you remove all the polygons in the base and then Mesh the plane, MeshSPlit works.
Then, you can use PatchSingleFace, zooming in carefully on each side to make one bridging polygon across the whole base of each half:
Then, FillMeshHole twice
and some cleanup with
'UnifyMeshNormals`
and here, I get a decent result.
Rhino’s mesh intersection tools, needed for the split etc, are not very robust and frequently need some extra help with even good meshes, which this was not…
