Hey 
I am trying to split a large topography mesh down into quadrants. I have managed to achieved this in some parts of the mesh, however it is failing on others. I am operating on a Mac, Rhino 7. I will attach all the files below, I only have a few more cuts to do but I am unsure how to get there. Apologies if this is a basic question.
