Cutting Volume Griddle Mesh with Surface Mesh

Hello everyone,

I’m trying to cut a volume mesh (generated with griddle) using a surface mesh (lithology remeshed with griddle), but the _MeshSplit command doesn’t seem to work. The volume is a closed mesh and it’s the first time I’m facing this issue.

Has anyone encountered the same problem ?

Hi @Zakaria

This appears to be an issue with Rhino functionality, so I would first try restarting the application and see if that resolves the issue.

There are also some other things to consider when working with the _MeshSplit command.

  • Keep in mind what tolerance parameter you are using. If Tolerance=Literal, the issue could be due to the absolute tolerance of your model
  • In order to properly split, the “cutting” object must pass through the domain completely
  • When working with more complex geometries, it sometimes helps to first intersect the meshes with _GInt Tolerance=0 before proceeding with the split. This can result in a cleaner separation; however the geometries you are using seem to be quite simple, so I do not suspect that is the issue here

Based on my experience, the meshsplit function may not work if a closed-volume mesh is grouped. I hope this is helpful.

You can solve it by ungrouping the object that is grouped.
