Form Data

The examples shown in this section were created using RV2 v1.0.0. They will be updated soon, and be compatible with the latest release of RV2.

To avoid having to process the session file over and over again to extract the information about the form diagram, we export the Form Diagram data to a separate JSON file (form.json) that can then be used as input instead. We also draw the form diagram as a simple mesh in Rhino.

import json
from compas.utilities import DataDecoder
from compas_rv2.datastructures import FormDiagram
from compas_rhino.artists import MeshArtist

FILE_I = 'bm-3.rv2'
FILE_O = 'form.json'

with open(FILE_I, 'r') as f:
    session = json.load(f, cls=DataDecoder)

form = FormDiagram.from_data(session['data']['form'])
form.to_json(FILE_O)

artist = MeshArtist(form, layer="RV2::Mesh")
artist.clear_layer()
artist.draw_faces(join_faces=True)
artist.redraw()

After exporting the data we can create the form diagram as follows.

from compas_rv2.datastructures import FormDiagram

form = FormDiagram.from_json('form.json')
