Hello there, I have just recently started using the Rhino Vault from the Github tutorial and successfully reached the point where I was able to create the Roof’s Mesh I wanted. Now exploring the website - I came across the Materialization scripts provided ( Rhinovault\_session.json ) and wanted to know if its possible to somehow import the mesh I produced into that so I can get the divided hexagonal blocks with shear keys. ![Shell Output](https://us1.discourse-cdn.com/flex015/uploads/compas_framework1/original/1X/488f0b9fdbfb268c989d2d9a7d57e05d8da98f68.png) ---

Yes, did you try to follow the tutorial and save your rhino session file? > **[Materialization | RhinoVAULT](https://blockresearchgroup.gitbook.io/rhinovault/next-steps/materialization)** ---

Hey @petrasvestartas, Yes I did save the Rhino vault session of this roof. I am confused where do I input this saved session in the step by step tutorial provided. ---

As gif shows it is in the same folder: ![](https://us1.discourse-cdn.com/flex015/uploads/compas_framework1/original/1X/a53098e7a908e20c2a2da04e953956a54f7d1016.jpeg) The saved session file (json file) is referenced in the python script: ```python #! python3 # venv: brg-csd # r: compas_rv import pathlib import compas from compas.scene import Scene # ============================================================================= # Load data # ============================================================================= IFILE = pathlib.Path( __file__ ).parent / "rhinovault_session.json" rv_session = compas.json_load(IFILE) rv_scene: Scene = rv_session["scene"] pattern = rv_scene.find_by_name("Pattern").mesh # ============================================================================= # Visualisation # ============================================================================= scene = Scene() scene.clear_context() scene.add(rv_scene.find_by_name("Pattern").mesh) scene.draw() ``` This line says that the session file is in the same folder as the python script: ```auto IFILE = pathlib.Path( __file__ ).parent / "rhinovault_session.json" ``` ---

Hey @petrasvestartas, thanks for the promt reply. I tried saving my Rhino Vault Session under the same name " rhinovault\_session.json" even adding the “.Json” suffix and its working now. Thanks for pointing that out. Out of the 12 steps I got to run the first 2 scripts of “000.Pattern” and "001.mesh " successfully. The moment I tried the next script " 002.remesh " script it gave me an error. ![error](https://us1.discourse-cdn.com/flex015/uploads/compas_framework1/original/1X/aaf17317c8ea94e61ec23ee6d897bedc941415a2.jpeg) How do I tackle this ? Do I need to know basic scripting in python to go ahead ? ---

hi, could you post the json file so i can run it locally? thanks! ---

Hello Tom, Thanks for replying. I have been updating the form so had to wait before i send you the json file. This the what i have been working on. ![final roof form](https://us1.discourse-cdn.com/flex015/uploads/compas_framework1/original/1X/bfeba08ba5d70f4abec624c9d022804549132dfe.jpeg) Btw I am unable to upload the JSON file here so here’s a link - [RhinoVAULT - Roof -2\_vertical thrust with modifications - 4 - Google Drive](https://drive.google.com/file/d/1UTqaFbatSwkYqABo445F8VcwB94iRmSP/view?usp=sharing) ---

hi, i haven’t looked at the details of the script in the RV docs, but i assume it uses an older version of the remeshing function. here is an updated version that uses `compas_cgal` instead. you can just run it in VS Code in an environment that has both `compas_rv` and `compas_cgal` installed… ```python import pathlib from compas_cgal.meshing import mesh_remesh from compas_viewer import Viewer import compas from compas.datastructures import Mesh from compas.scene import MeshObject from compas.scene import Scene file = pathlib.Path( __file__ ).parent / "RhinoVAULT - Roof -2_vertical thrust with modifications - 4.json" session = compas.json_load(file) scene: Scene = session["scene"] meshobj: MeshObject = scene.get_node_by_name("ThrustDiagram") mesh: Mesh = meshobj.mesh for face in list(mesh.faces_where(_is_loaded=False)): mesh.delete_face(face) length = sum(mesh.edge_length(edge) for edge in mesh.edges()) / mesh.number_of_edges() mesh.quads_to_triangles() V, F = mesh.to_vertices_and_faces() V, F = mesh_remesh((V, F), target_edge_length=length) mesh = Mesh.from_vertices_and_faces(V, F) viewer = Viewer() viewer.scene.add(mesh) viewer.show() ``` It should produce the following result (press F once the viewer pops up to zoom to the extents of the mesh) ![Screenshot 2025-05-07 at 20.53.03](https://us1.discourse-cdn.com/flex015/uploads/compas_framework1/original/1X/df676b2b0e81bd08f3f2bf774368c53c8f2891b2.jpeg) let me know if you need help getting this to work. we will update the RV docs asap…
