Thank you Anders for getting back to me!
As I understand with the partition mesh function, it only allows for maximum values of meshes and is culling the rest of the mesh faces? This would be difficult for a domain such as 50-97 for instance as the first 50 faces would remain in this example. Maybe I’m wrong, but I am noob with coding!
The problem with the duplicating method as you mentioned is that if a mesh is heavy such as a completely joined building entity then duplicating requires serious computational power. The other issue with cull function is it too is relatively heavy when dealing with large mesh face counts. Constructing a mesh however is much quicker when only supplying the face’s and then later culling unused vertices, however, this methodology requires duplicating the host mesh multiple times
