[BUG] Notebook examples - AttributeError: 'Loop3DView' object has no attribute 'add_scalar_field' or 'add_isosurface' #263
Description
Describe your issue
Working with LoopStructural v1.6.16, I get the AttributeError: 'Loop3DView' object has no attribute 'add_scalar_field' or AttributeError: 'Loop3DView' object has no attribute 'add_isosurface'
when running the provided example notebooks (2b. Refolded folds, 3a. Modelling faults using structural frames, 3c. Defining the fault displacement function)
Minimal reproducing code example

This example wasn't updated for the new visualisation using pyvista. I've updated it and the docs are being re-run.

After upgrading to 1.6.18, I still have a few similar errors in some notebooks (downloaded from the last built of the doc) and python scripts (downloaded from github).
Assignining model.create_and_add_foliation to a strati object (among others), and updating the call to the viewer solves it.
