How to make changes in geometry and mesh from case file
 

Hi.
I have a cas file containing a project with an advanced mesh (Hexagonal mesh). I only have the cas file for this project, and nothing else.
I would like to make a similar project but with a minor change in the geometry, and thus need to regenerate the mesh.
I have the geometry file for the geometry with the minor change, but I would prefer not to make the mesh again for the new project.
Is there a way to export the mesh and apply it on the new geometry?
Or can I somehow extract the steps to create the mesh?
